Thank you for reaching out to Microsoft Q&A.
When this error occurs (Error Code 715-123420 or 555420), it indicates that Azure AI Foundry has blocked GPT model deployment due to a fraud signal, and the request requires review by the appropriate internal team.
To proceed with further investigation and escalation, could you please share the details requested in private message for the same.
Thankyou!
