I have a new Azure subscription in which I am trying to deploy models to a new Foundry project. Unfortunately, the attempts to deploy the model have all failed with the following pattern of errors:

715-123420: Our system has detected this request as unusual activity for your account. If you are confident this is in error, please contact support.

Trace ID : 57a9f9ce-934c-44e2-8a0b-60e7cef21147

Client request ID : 3f4a12a6-45b3-4320-bbbd-b84bea9bc02d

Service request ID : 5c6859a6-4782-4be1-b8f7-aa29410a2111

I have tried a variety of models but the result is always this (I avoided models which don't have any quota). I finally was able to deploy gpt-oss-120b but I cannot update it after the creation; the error is the same.

The resource names are:

    • ai-foundry-westus2-1 (West US 2)
    • ai-foundry-eastus1-1 (East US)

From previous threads on similar subject, there is probably some subscription level allow-listing needed. Please help unblock this. Thank you in advance.
