Looks like a transient issue as per error trace.

Does the issue still persists at your side - Have you retried recently

Have you tested other regions. Please share your region/TPM setting to be in same page.

Are the resource network protected by virtual network.

Looking forward to hearing from you.

Thank you.

Hello, I am also unable to deploy any model. I have tried East US and UK south so far, all not working.

On foundry:

715-123420: An error occurred. Please reach out to support for additional assistance.

...

And on Open AI:

Failed to deploy model gpt-4.1 715-123420: An error occurred. Please reach out to support for additional assistance. Trace ID : 5e57fa0e-dd62-40bf-8872-bdb451dce966Client request ID : aa38d901-a7a1-4f06-99a4-890acc1365b4Service request ID : 50b7cfe7-e45f-4e5b-b41d-5cdcde3fe06e

Someone please kindly advise, as my clients are running on gpt-4o which is about to be deprecated!

Answer 2

Hi Paul Gainer Internal

Came to know that Error Code 715-123420, normally indicates a potential fraud-related block enforced Realtime Fraud Protection (RTFP).

Need to create a collaboration ticket in Fraud Response operation team to unblock the GPT deployment

If it is not a finetuned model, you can create a new model in new /existing foundry project to continue.

If you still need assistance. Please share the details requested in private message for support ticket creation.

Thank you.
