The Microsoft Entra ID Graph API service is being retired. This retirement affects all Azure Stack Hub customers, and requires you to run the script included in this article for all affected applications.

Compute

Azure Kubernetes Service on Azure Stack Hub

  • Applicable: This issue applies to release 2311 and later.
  • Cause: Azure Kubernetes Service on Azure Stack Hub, currently in preview, is being discontinued and won't be released to general availability. If you try to register a new subscription to the Microsoft.Containerservice resource provider, the registration stays in the Registering state. If you try to create a new managed Kubernetes cluster or access existing managed Kubernetes clusters, you might see the raining cloud error screen.
  • Remediation: Microsoft is aware of the problem and is working on a fix.
  • Occurrence: Common.

Graph API retirement

  • Applicable: This issue applies to all supported versions of Azure Stack Hub.
  • Cause: The Microsoft Entra ID Graph API service is being retired.
  • Remediation: Run the script included in this article for all impacted applications. The script sets a flag that configures these applications for an extension that allows these specific applications to continue calling the legacy Graph API until June 2025.
  • Occurrence: Occasional.

Networking

Outbound ICMP to internet is blocked by default for tenant VM

  • Applicable: This issue applies to release 2311 and later.
  • Cause: The issue is caused by a change in the default ICMP behavior introduced with Windows Server 2022 that diverges from previous behavior, as well as Azure behavior.
  • Remediation: You can add an inbound NSG rule to allow outbound ICMP packets to the internet. Microsoft is aware of the issue.
  • Occurrence: Common.

  • Remediation: Microsoft is aware of the issue and is working on a fix.
  • Occurrence: Common.

A-series VMs deprecated

  • Applicable: This issue applies to release 2406 and later.
  • Cause: The A-series VMs are deprecated in Azure, so they shouldn't be used in Azure Stack Hub.
  • Remediation: Although Azure Stack Hub isn't removing the A-series SKU, other undefined behavior might occur if you continue using it (such as with the load balancer, VMSS, etc.). Therefore, you should use a different VM SKU when you're ready. There is no cost difference in using different VM SKUs on Azure Stack Hub.
  • Occurrence: Common.

ESv3 and DSv3 series don't have nested virtualization enabled

  • Applicable: This issue applies to release 2408.
  • Cause: Neither of the newly introduced ESv3 or DSv3 series; for example, E20s_v3, has nested virtualization enabled.
  • Remediation: Microsoft is aware of the issue and is working on a fix.
  • Occurrence: Common.

  • Remediation: Microsoft is aware of the issue and is working on a fix.
  • Occurrence: Common.

Nodes blade fails to load

  • Applicable: This issue applies to release 2311 and later.
  • Cause: The Nodes blade on the portal fails to load when a GPU property isn't configured.
  • Remediation: Microsoft is aware of the issue and is working on a fix.
  • Occurrence: Occasional.
