My watch button doesn’t work. What am I missing?
Hello all, I’m new to JSON/Sharepoint. I’ve pieced together a formatting that I like but I can’t get the watch button to work. ChatGPT said something about a button element not able to be used to open link. But I tried a div to look like a button but it didn’t work either.
Can anyone help me correct the code? The code in question starts at line 250.
I’m trying to make this elmtype link to the $Link column.

Issue with Provision Command in Teams Toolkit for Copilot Plugin
Hello,
I am writing to seek assistance with an issue I am encountering while using the Teams Toolkit in Visual Studio Code. I have made a prototype of a Copilot Plugin. I need to publish it for our company for testing. However, when I try to execute the Provision command, I repeatedly receive the error: “We couldn’t find a subscription.”
I have double-checked and confirmed that I have the Contributor role in the subscription (Pay-As-You-Go). I have selected it in both the Azure Portal and Visual Studio Code, but I still get this error.
Could someone please assist me in resolving this issue? Any guidance or suggestions on what I might be missing would be greatly appreciated.
Best regards,
Anton

I’ve been looking and the Conditional Access Policy for Token Protection but before implementing I checked Azure Sign-In logs. What I found is that when I use mu admin credentials (different than my user credentials) to access for example Azure Portal, Token Protection Sign in Session value is “Unbound”. When I use my standard user, all sign ins are logged with the Token value “bound”. We use hybrid joined devices. I have checked with my colleague and his Token Protection values are always “bound”, no matter if he uses his standard or admin account. What can be the reason? I cannot find much information about how to troubleshoot it. I’m worried that when I enable CA policy, I will cut myself off.

Troubleshooting Cross-Tenant Mailbox Migrations
In Part 1 of this series, we talked about cross-tenant (sometimes referred to tenant to tenant or T2T) mailbox migrations. In Part 2, we’ll cover how to troubleshoot issues you may encounter during cross-tenant mailbox migrations. There are several tools we wanted to mention that can be useful when troubleshooting.
Here is a table with the key elements:
We cannot stress enough how important it is to ensure the configuration is correct. Ensuring this saves time!
T2T migration errors and fixes
The most common errors in T2T migrations and how to address them. The errors are found using Test-MigrationServerAvailability or Get-MigrationUserStatistics / Get-MoveRequestStatistics.
Test-MigrationServerAvailability
This simulates a move request cross-tenant and will identify configuration issues at user level. When you get the same error for multiple users, it is likely that configuration is incorrect at organization level.
Powerful commands to troubleshoot your migrations and verify progress. The -IncludeReport report is basically a move report which shows all the things that happened in the migration. -DiagnosticInfo provides information on durations, throttling and possible underlying causes for stalls.
Cross tenant mailbox migration validation script
The report will check user level organization level configuration for T2T migration so that you are prepared for migrations.
Permissions related cmdlets:
Know what permissions are migrated in Exchange Online and if they are broken.
Data Consistency Score in migrations
Sometimes, we cannot migrate all the data from source to target, so we skip it. There are 4 main categories of skipped items:
Bad / corrupt items,
Large items (MaxReceiveSize up to 150MB in Exchange Online),
Missing items in the target (which normally doesn’t happen in move requests where the target mailbox is locked until completion and the end-user or other processed wouldn’t be able to access the target mailbox at all),
Other category issues.
You can view what has been skipped (for example permissions that couldn’t be mapped to a user are considered bad items) in move reports. Sometimes, if there is significant data loss (not migrated), the admin will need to approve to complete migration.
Duration estimates for T2T migrations based on data retrieved for 50% (P50) and 90% (P90) of the statistics seen for that migration type. If you exceed P90, your migration may be slow.
Test-MigrationServerAvailability
A very useful tool when troubleshooting cross-tenant mailbox migration is Test-MigrationServerAvailability. You run this command in the target tenant after the migration endpoint has been created. You can run Get-MigrationEndpoint to view the identity of the endpoint.
Test-MigrationServerAvailabiliy -TestMailbox <user@contoso.com> -Endpoint <T2T Migration Endpoint Name>
If the Result is Success, you can proceed with the migration of the user.
Note that a successful test doesn’t guarantee you will be able to migrate the user without any issues, but it is a good starting point to ensure the minimum prerequisites are met.
For a list of common failures, please see the Migration Failures section here: Cross-tenant mailbox migration
Here is an example, a situation where the source archive mailbox is a few bytes over 100GB.
Test-MigrationServerAvailability in target tenant:
Mailbox statistics for archive in the source tenant:
In situations where a source primary, archive, or dumpster is larger than the target tenant’s user quotas you will see errors like ArchiveExceedsTargetQuotaPermanentException, MailboxExceedsTargetQuotaPermanentException, or ArchiveDumpsterExceedsTargetQuotaPermanentException. In this case, you can contact Microsoft support for recommendations and see which options are best for you. Support may be able to provide an exception for an individual mailbox (we cannot process bulk mailboxes) and if you plan on having auto-expanding on the target tenant side and allocate room to grow in the target tenant. Depending on the situation and if you have enabled the auto-expanding archive feature on the source tenant, you can wait until the AuxArchive is provisioned and MainArchive / primary mailbox size is reduced below the 100GB quota (this can take up to 30 days but it’s generally 7 days on average). Or, if possible, ask the user to clean up unnecessary data in the source mailboxes if auto-expanding is not an option in the target tenant. Sometimes, source mailboxes that are or were on hold at some point, have Recoverable Items quota set to 100GB as opposed to the default 30GB, and in this case, you might just want to enable litigation hold on the target tenant mail user to also increase the quotas there.
Coming back to Test-MigrationServerAvailability, if this fails for multiple users, then likely there is something wrong at the organization level and the cross-tenant mailbox migration validation script discussed in the next section can be helpful. For example, if you get an ‘Access is denied’ error (screenshot below) for some or all users, here are some possible causes at organization level:
Erroneous application registration;
Wrong credentials or expired credentials used in the migration endpoint; or
Source tenant organization relationship’s OAuthApplicationId does not match target migration endpoint’s ApplicationId, or the org relationship is not using tenant ID in DomainNames
CrossTenantMailboxMigrationValidation script
When it comes to validating a large cross-tenant mailbox migration (CTMM), a better tool you can rely on is the Cross-Tenant Mailbox Migration validation script written by Alberto Pascual Montoya, published in the official CSS-Exchange GitHub repo and referenced by our official CTMM documentation.
This script will check and validate various related user and organization settings. It is very useful to run it before CTMM takes place to ensure the mailbox(es) can be migrated, and if they can, that they won’t face any validation issues during the move.
You can run the script to validate the configuration between both organizations by running:
.CrossTenantMailboxMigrationValidation.ps1 -CheckOrgs -LogPath <LogFileLocation>
You can also run it to validate the objects on the target tenant by comparing them with the objects in the source tenant by running:
.CrossTenantMailboxMigrationValidation.ps1 -CheckObjects -CSV <CSVFileLocation> -LogPath <LogFileLocation>
As you can see below, it will highlight any discrepancies found, and if the target object is not synced from any AD, it will ask if you would like to correct the discrepancy on the go:
There are other scenarios covered by the script too. For example, running it only from the source tenant side and collecting the needed data that can be sent to the target tenant admins and they run the script against their tenant; or simply collecting the data for support purposes.
Analyzing migration reports
Move request and migration user Exchange Online PowerShell commands are other tools that can help us troubleshoot cross-tenant migration.
Let’s do a quick walkthrough of these commands:
When we create a new migration batch, in the background, a Get-MigrationUser object is created for each user specified in the CSV file for migration. If things go well during a partial validation, a Get-MoveRequest is created for each MigrationUser.
In the example below, we can see that we have a migration batch (Get-MigrationBatch) with 1 user (one user was specified in the CSV file) and a migration user object (Get-MigrationUser) was created for the user, but because we don’t have a mail user with this identity, we failed the migration at this early stage. The move request was not created (Get-MoveRequest fails).
This user is not found at all on the target tenant (wrong identity of the user in the CSV):
And if I had run Test-MigrationServerAvailability on the EmailAddress specified in the CSV, before creating the batch, the error would have been relatively obvious:
Also, you’d want to ensure that the users specified in the migration CSV file don’t have a move request already (or they are not a part of another batch).
There might be situations where you might see that migration is stuck at creating the move request, that is in injection workflow stage:
If State: Waiting takes too long, you can look at DiagnosticInfo on Get-MigrationUserStatistics (check the Durations section in this blog post for more info) to see if you have more information on where migration is stuck.
In this case, we can see that it waited 19 minutes to inject the move request:
And 0 move requests injected successfully since we have 0 InjectedRequestCount and no timestamp at LastSuccessfulInjectionTime or LastInjectionTime.
After waiting 19 minutes for the injection of the move request, we finally got a permanent failure: ErrorCrossTenantSourceUserIsInHoldOrRetentionPolicyAppliedPermanentException, and the service gave up trying to inject the move request. The lesson is to check Test-MigrationServerAvailability before creating the batch (prerequisite missed) and avoid this waiting time and failure that could have been easily detected.
You might wonder when we use Get-MigrationUserStatistics versus Get-MoveRequestStatistics. It mostly depends on preference. I am more used to Get-MoveRequestStatistics, but in the situation where we don’t have a Get-MoveRequest created (like in the example above), we are forced to use Get-MigrationUserStatistics. Normally I append -DiagnosticInfo “verbose,showtimeslots” to make sure I get the most details. Also, if you are looking to check skipped Items, you will append -IncludeSkippedItems to Get-MigrationUserStatistics. If using Get-MoveRequestStatistics, it is enough to use -IncludeReport.
Let’s take another example where a move request was injected successfully by the service (New-MoveRequest) but this one failed. We will troubleshoot using the Get-MoveRequestStatistics command (since we have a Get-MoveRequest in place):
Move requests in cross-tenant migrations will have Onboarding_CrossTenant WorkloadType and the SourceServer and TargetServer are Exchange Online servers, usually in different forests.
In this case, the move request failed because we don’t have the Cross-tenant User Data Migration license on source or target tenant.
Get-MoveRequestStatistics EXOMailbox1 |FL MailboxIdentity, WorkloadType, SourceServer, TargetServer, RemoteHostName, FailureType, Message, FailureTimestamp
If I want to check the full details of the failure, I can run a command like this:
$stats = Get-MoveRequestStatistics <User> -IncludeReport
$stats.Report.Failures
If you’d want to have a quick overview of failures encountered, you would run:
$stats.Report.Failures | group Failuretype | FT -a
To check if any items would be skipped during the move, you can run the following command:
Get-MoveRequestStatistics <User> | FL DataConsistency*, BadItem*, LargeItem*, MissingItem*, Skipped*
For more information on DCS (Data Consistency Score) please see Improving Migrations Using Data Consistency Scoring and Track and prevent migration data loss. For troubleshooting DCS and approving skipped items, please see Migrations with Data Consistency Score (DCS) – more than you ever wanted to know! – Microsoft Community Hub.
If you need to look at the available properties of the source or target user before and after the move, you can use the IncludeReport switch in Get-MoveRequestStatistics.
Run the following in the target tenant after move is completed:
$stats = Get-MoveRequestStatistics <User> -IncludeReport
Then you would look into the properties like this:
$stats.report.SourceMailboxBeforeMove.Props
$stats.report.TargetMailUserBeforeMove.Props
$stats.report.SourceMailuserAfterMove.Props
$stats.report.TargetMailboxAfterMove.Props
Suppose that we want to see if migration service stamped the ExternalEmailAddress on the source recipient after the move (according to the TargetDeliveryDomain set in the migration batch), we would run this command:
$stats.report.SourceMailUserAfterMove.Props | ? PropertyName -eq “ExternalEmailAddress” | FL PropertyName, Values
Troubleshooting migration of permissions
Let’s teach you how to examine migration reports to see if permissions were migrated correctly and if there are any permissions errors in move reports. We provide PowerShell commands for the target tenant to help corroborate outputs with the migration reports analysis.
We will first check mailbox Full Access permissions, which should move during the cross-tenant migration, and we check them by using the move reports and PowerShell commands.
In this example, we moved MyMailbox10 and MyMailbox19, from one tenant to another:
We can see that MyMailbox10 has maintained the FullAccess permission on MyMailbox19 after migration:
We can confirm this by looking at the property called ExchangeSecurityDescriptor (which is MsExchMailboxSecurityDescriptor in AD) and noticing the SID values in there.
Note: you first need to store the Get-MoveRequestStatistics <user> -IncludeReport into a variable, in this example $stats19.
$stats.Report.SourceMailboxBeforeMove.Props | ? PropertyName -eq “ExchangeSecuritydescriptor”
$stats.Report.TargetMailboxAfterMove.Props | ? PropertyName -eq “ExchangeSecuritydescriptor”
Source mailbox: before move the SID belongs to MyMailbox10 in the source tenant.
Target mailbox: after move the SID belongs to MyMailbox10 in the target tenant.
If you have multiple SID values listed here, you can use these commands to display them in a more readable format:
$valueAfterMove = ($stats19.Report.TargetMailboxAfterMove.Props | ? PropertyName -eq “ExchangeSecurityDescriptor”).values.Strvalue
$sdobj = New-Object System.Security.AccessControl.RawSecurityDescriptor($valueAfterMove)
$sdObj.DiscretionaryAcl | select -Skip 1 |FT AceQualifier,AccessMask, SecurityIdentifier, AceFlags, IsInherited
The AccessMask 1 here means Full Access Permission:
The same information is also available in the DebugEntries in the move report when we look for “MailboxSecurityDescriptor’.
$stats.report.DebugEntries | ? LocalizedString -match “MailboxSecurityDescriptor”| % {[string] $_}
Besides Get-MailboxPermission cmdlet, we can look at the ExchangeSecurityDescriptor property with the Get-Mailbox command:
get-mailbox mymailbox19 | select -ExpandProperty ExchangeSecurityDescriptor | select -ExpandProperty discretionaryACL
A quick reminder that Send on Behalf permissions are NOT migrated, so we won’t see anything in move reports.
Send As permissions
The Send-As permissions are migrated. In target tenant, after migration:
You can similarly check the permissions in the source tenant.
When checking the move reports for Send-As permission, you can put the DebugEntries in a Notepad++ file and search for the user’s SID (source user SID and target user SID). These permissions would fall into the category UserSecurityDescriptor. You might see many AD permissions (screenshot below where entries were separated by new line), so it can be quite hard to spot them.
If you want to list all SIDs with Send-As, you can search specifically for ‘CR’ and the following GUID: ab721a54-1e2f-11d0-9819-00aa0040529b.
$stats.report.DebugEntries | ? LocalizedString -match “UserSecurityDescriptor”| % {[string] $_} | clip
Then paste from clipboard to Notepad++, for example:
To have them listed on new lines, you can do the following:
(OA; replace with n(OA;
(A; replace with n(A;
(OD; replace with n(OD;
These are called Ace Types, for a full list see documentation.
Then, since Send-As is an Extended Right, we will see CR ab721a54-1e2f-11d0-9819-00aa0040529b, which is the SendAs Extended Right GUID.
Checking the first SID in the source tenant:
Checking the first SID in the target tenant:
On-premises, looking at the LDP dump of the security descriptor of the user, you would see something like this:
Mailbox folder permissions
We also migrate mailbox folder permissions.
In the target tenant, after migration, you will run Get-MailboxFolderPermission <user>:<Folder> to check permissions present. For example:
Based on this output alone, we would think that there are no permissions issues.
But expand the User property and notice that Cloud3 is of Unknown user type:
And, if we check the move report, we will see TargetPrincipal errors and FolderACL issues for cloud3.
In this case, the DataConsistencyScore is usually Good instead of Perfect, and we will have corresponding BadItems and Failures recorded if we don’t find the principal user with permissions, in the target tenant.
Here is a quick command to see the alias of the principal user that is not found in the target tenant (Cloud3 in our example).
$stats.report.BadItems | select Kind, Folder, ScoringClassifications, {$_.Failure.DataContext} | ft -a
We can further look into DataContext with |FT or |FL for full details:
$stats.report.BadItems | select {$_.Failure.DataContext} | ft -a
Or look at the entire failure on specific bad items. BadItems[1] is the second CorruptFolderAcl in the screenshot above (the first line count starts from 0, not 1).
$stats.report.BadItems[1].Failure
For migration of Calendar and FreeBusy data folder permissions entries, we can look at folder ACL in Report.DebugEntries:
$stats.report.DebugEntries | ? LocalizedString -match “FolderAcl”| % {[string] $_}
Checking migration durations
Now that you rock at troubleshooting migration of permissions (which was lengthy and a bit boring), we will get into another topic: duration of the cross-tenant migrations and when to recognize you have an issue.
To see how much time your migration took and how it is progressing, you can run these commands:
$stats = Get-MoveRequestStatistics <User> -IncludeReport -DiagnosticInfo “Verbose,showtimeslots”
$stats |FL *duration*
In my example, I see that overall duration was about 30 minutes (it was a very small 35 MB mailbox) but I have 51 days of TotalFailedDuration:
If I check the $stats.DiagnosticInfo property, we will see these durations in a more detailed and accurate way:
Overall Move = 57 days (about 2 months) and 28 min, out of which:
In Progress = 6 min (actual copying of the data)
Suspended = 21 min (I chose to complete it at a certain point after initial sync, so it went into suspended mode)
Failed = 51 days and about 8 hours (it was in a failed state for 51 days)
Completed = 5 days and 16 hours (the move completed 5 days ago but I ran the Get-MoveRequest command now, 5 days after completion)
You can check the table from Microsoft 365 and Office 365 migration performance and best practices | Microsoft Learn for duration estimates during mailbox migrations in Exchange Online.
For example, a mailbox with a size of less than 10 GB is estimated to be migrated within 1 day. You can open a case with Microsoft Support if P90 is exceeded and it is because of our service (for example it is not a configuration issue on your side that wasn’t remediated fast enough).
In my situation above, I had a permanent failure, and left the move sit there for 51 days in a Failed state. This doesn’t count against the P90, as I neglected the move. The InProgress duration was 6 min for my 35MB mailbox which meets the P90 estimation (90% of mailbox migrations less than 10GB would complete in 1 day).

Announcing advanced features for text to speech avatars
Text to speech avatar, previewed at Ignite 2023, enables users to create realistic videos of speaking avatars simply by giving text input and allows users to create real-time interactive bots with visual elements that are more engaging. Since its preview, we have received great feedback and appreciation from customers in various industries. Today, we are glad to share what’s been added to the avatar portfolio.
More prebuilt avatar options and more regions available
Our prebuilt text-to-speech avatars offer ready-to-deploy solutions for our customers. We’ve recently enriched our portfolio’s diversity by introducing five new avatars. They can be used for both batch synthesis and real-time conversational scenarios. We remain committed to expanding our avatar collections to encompass a broader range of cultures and visual identities.
Text to speech avatars
These newly introduced avatars can be accessed in Speech Studio for video creation and live chats. Dive deeper into the process of synthesizing a text-to-speech avatar using Speech SDK for real-time synthesis in chatbot interactions, or batch synthesis for generating creativity videos.
Beyond the previously available service regions – West US 2, West Europe, and Southeast Asia – we are excited to announce the expansion of our avatar service to three additional regions: Sweden Central, North Europe, and South Central US. Learn more here.
Enhanced text to speech avatar chat experience with Azure OpenAI capabilities
Text-to-speech avatars are increasingly leveraged for live chatbots, with many of our customers utilizing Azure OpenAI to develop customer service bots, virtual assistants, AI educators, and virtual tourist guides, among others. These avatars, with their lifelike appearance and natural sounding neural TTS or custom voice, combined with the advanced natural language processing capabilities of the Azure OpenAI GPT model, provide an interaction experience that closely mirrors human conversation.
The Azure OpenAI GPT-4o model is now part of the live chat avatar application in Speech Studio. This allows users to see firsthand the collaborative functioning of the live chat avatar and Azure OpenAI GPT-4o. Additionally, we provide sample code to aid in integrating the text-to-speech avatar with the GPT-4o model. Learn more about how to create lifelike chatbots with real-time avatars and Azure OpenAI GPTs, or dive into code samples here (JS code sample, and python code sample) .
This update also includes sample codes to assist in customizing Azure OpenAI GPT on your data. Azure OpenAI On Your Data is a new feature that enables users to tailor the chatbot’s responses according to their unique data source. This proves especially beneficial for enterprise customers aiming to develop an avatar-based live chat application capable of addressing business-specific queries from clients. For guidance on creating a live chat app using Azure OpenAI On Your Data, please refer to this sample code (search “On Your Data”).
More Responsible AI support for avatars
Ensuring responsibility in both the development and delivery of AI products is a core value for us. In line with this, we’ve introduced two features to bolster the responsible AI support for text-to-speech avatars, supplementing our existing transparency note, code of conduct, and disclosure guidelines.
We’ve integrated Azure AI Content Safety into the batch synthesis process of text to speech avatars for video creation scenarios. This added layer of text moderation allows for the detection of offensive, risky, or undesirable text input, thereby preventing the avatar from producing harmful output. The text moderation feature spans multiple categories, including sexual, violent, hate, self-harm content, and more. It’s available for batch synthesis of text-to-speech avatars both in Speech Studio and via the batch synthesis API.
In our bid to provide audiences with clearer insights into the source and history of video content created by text to speech avatars, we’ve adopted the Coalition for Content Provenance and Authenticity (C2PA) Standard. This standard offers transparent information about AI-generation of video content. For more details on the integration of C2PA with text to speech avatars, refer to Content Credentials in Azure Text to Speech Avatar .
Unlocking real-time speech synthesis with the new text stream API
Our latest release introduces an innovative Text Stream API designed to harness the power of real-time text processing to generate speech with unprecedented speed. This new API is perfect for dynamic text vocalization, such as reading outputs from AI models like GPT in real-time.
The Text Stream API represents a significant leap forward from traditional non-text stream TTS technologies. By accepting input in chunks (as opposed to whole responses), it significantly reduces the latency that typically hinders seamless audio synthesis.
Comparison: Non-Text Stream vs. Text Stream
Non-Text Stream
Text Stream
Input Type
Whole GPT response
Each GPT output chunk
TTS First Byte Latency
High (Total GPT response time + TTS time)
Low (Few GPT chunks time + TTS time)
The Text Stream API not only minimizes latency but also enhances the fluidity and responsiveness of real-time speech outputs, making it an ideal choice for interactive applications, live events, and responsive AI-driven dialogues.
Utilizing the Text Stream API is straightforward. Simply follow the steps provided with the Speech SDK. For detailed implementation, see the sample code on GitHub.

Arc Length Continuation Method: Numerical Method
I am trying plot a curve (frequency vs amplitude) that has a (sn) birfurcation, and I am trying to write a code that would use the Arc Length Continuation to get the solve the nonlinear equations and get the (frequency response) curve (include regions where two solutions exist).
The methodology is as follows
Initialization and Initial Guess: Find an initial guess for a specific omega (parameter)
Residual Calculation: Using a function handle to calculate residuals, based on the nonlinear equation
Newton-Raphson Solver: Solves the nonlinear equation using the Newton-Raphson method.
Continuation Method: Continuation method uses the arc length continuation to trace the solution curve by extrapolating new guesses and solving using the Newton-Raphson method.
Arc Length Constraint: Ensures the next step in the continuation process is a fixed arc length from the current solution.
Plotting: Code for plotting the FRF is included but commented out because the code is incomplete
My issue is in the function called continuation–which continunes to solve for nSteps (number of steps), by calculating the new guess, and augemeniting the Jacobain to have the new constraint equation–I believe I have the correct(?) logic but my code is incorrect.
(I know there are straight-forward ways to obtain the FRF for the function defined in Analytic Equation, the reason I am testing it out on a straight-forward equation is to make sure it is running correctly.
Any pointers appreciated

endI am trying plot a curve (frequency vs amplitude) that has a (sn) birfurcation, and I am trying to write a code that would use the Arc Length Continuation to get the solve the nonlinear equations and get the (frequency response) curve (include regions where two solutions exist).
The methodology is as follows
Initialization and Initial Guess: Find an initial guess for a specific omega (parameter)
Residual Calculation: Using a function handle to calculate residuals, based on the nonlinear equation
Newton-Raphson Solver: Solves the nonlinear equation using the Newton-Raphson method.
Continuation Method: Continuation method uses the arc length continuation to trace the solution curve by extrapolating new guesses and solving using the Newton-Raphson method.
Arc Length Constraint: Ensures the next step in the continuation process is a fixed arc length from the current solution.
Plotting: Code for plotting the FRF is included but commented out because the code is incomplete
My issue is in the function called continuation–which continunes to solve for nSteps (number of steps), by calculating the new guess, and augemeniting the Jacobain to have the new constraint equation–I believe I have the correct(?) logic but my code is incorrect.
(I know there are straight-forward ways to obtain the FRF for the function defined in Analytic Equation, the reason I am testing it out on a straight-forward equation is to make sure it is running correctly.
Any pointers appreciated

Matlab Parallel pool test failure
I am using Matlab R2019b, I have setup an HPC cluster. In the validation stage, the last one (parallel pool test) fails. It shows the host IP refuses the connection. I tried some other IPs, still the same issue. Also, I have added the inbound rule in the firewall for Matlab and TCP ports 27370-27370.Also, on the left bottom corner of Matlab, starting parallel pool always fails too. I can also see my jobs sent to the HPC job manager, but I guess when the data coming back they are refused by my local IP.I am using Matlab R2019b, I have setup an HPC cluster.
