  • Azure region: westus2
  • Operation: Microsoft.MachineLearningServices/workspaces/onlineEndpoints/write
  • Azure CLI: 2.90.0
  • ML extension: 2.44.1
  • Endpoint accepted but ends in Failed
  • Deployment count: 0
  • Microsoft.Network, Microsoft.Cdn, Microsoft.PolicyInsights, and core Azure ML providers are registered
  • corelation IDs
    • Primary: 0d84ac12-4011-4ec0-8f86-5adc522a3fdc Secondary: 3f88bf3a-64a1-4059-a8ce-0f6e533cd629
  • both failure time stamps
    • both involve: Microsoft.MachineLearningServices/workspaces/onlineEndpoints/write
    • both returned: SubscriptionNotRegistered [N/A]
    • Azure Machine Learning managed online endpoint creation was attempted twice for the same endpoint, level8-bank-marketing-endpoint, in the westus2 region. The first endpoint-write operation failed on September 8, 2026, at 07:23:36.9028473 UTC, with correlation ID 3f88bf3a-64a1-4059-a8ce-0f6e533cd629. Azure returned SubscriptionNotRegistered [N/A]. After the initial failure, the relevant resource-provider states were reviewed. Microsoft.Network, which had initially been NotRegistered, was subsequently registered. The failed endpoint was removed, and endpoint creation was attempted again. The second endpoint-write operation failed on September 8, 2026, at 08:37:34.9741912 UTC, with correlation ID 0d84ac12-4011-4ec0-8f86-5adc522a3fdc. It returned the same SubscriptionNotRegistered [N/A] error. The second attempt therefore failed with the same error even after Microsoft.Network and the other relevant providers—including Microsoft.MachineLearningServices, Microsoft.Cdn, and Microsoft.PolicyInsights—were verified as registered. In both attempts, Azure accepted the endpoint-write operation but the endpoint entered the Failed provisioning state. No online deployment was created, no model container started, and no traffic was assigned.

    @Getamesay Zegeye - Thank you for confirming that the issue has been resolved: https://learn.microsoft.com/en-us/answers/questions/6004367/azure-ml-online-endpoint-fails-with-subscriptionno?page=1&orderby=Helpful&translated=false#answers

    Issue: When creating an Azure Machine Learning managed online endpoint in westus2.

    Azure accepts the endpoint write operation, but the endpoint enters Failed

    provisioning state with: SubscriptionNotRegistered

    Resource provider [N/A] isn't registered with Subscription [N/A].

    Resolution: After verifying the standard Azure ML providers, I found that Microsoft.Web was NotRegistered. I registered Microsoft.Web, waited for propagation, and created a new managed online endpoint named level8-bank-endpoint-r3.

    The endpoint creation completed successfully in westus2 with provisioning state Succeeded. The create command returned exit code 0, and the authoritative follow-up query also returned Succeeded.

    No deployment or traffic was created during this test. This strongly indicates that registration or propagation of Microsoft.Web resolved the earlier SubscriptionNotRegistered [N/A] endpoint-write failure.

    Please do let us know if you have any further questions or concerns. We’ll be happy to assist you.
