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

Ricardo Jorge Rebelo de Sousa 0

Region: Sweden Central

Existing deployments: GPT-5-mini / GPT-5 etc (working)

Failing deployment: GPT-5.4 (version 2026-03-05)

All attempts to deploy GPT-5.4 (or GPT-5.5 haven't tried other models) fail immediately with:

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

No additional error details are returned. The model appears in the Foundry catalog as GA and the Deploy button is available, but deployment fails every time.

Existing deployments (GPT-5 included) continue to work. The issue affects new deployments only.

I suspect this is an RTFP (Real-Time Fraud Prevention) block on the sponsorship subscription, similar to the issue reported in https://learn.microsoft.com/en-us/answers/questions/5825772/foundry-model-deployment-fails-with-715-123420-for. The Developer support plan only routes to Q&A — I cannot open a support ticket to request an unblock.

Requesting:

Confirmation of whether an RTFP flag is applied to my subscription
Removal of the block if confirmed
Guidance on deploying GPT-5.4 or other models we might need in the future

Subscription ID: [REDACTED — will share via DM if needed]

I just responded. This doesn't seem pinned in time. It happens whatever way I try to create the deployment.

Hi @Ricardo Jorge Rebelo de Sousa

We are coordinating with the PG team, and they have approved multiple events that were previously blocked. The team is currently working on resolving the issue.

Hi @Anshika Varshney @SRILAKSHMI C @Sina Salam I don't mean to be a pain but it's been nearly 2 weeks now and I still don't know how I can deploy these models which is slowing us down. Can I get an update?

Hello Ricardo Jorge Rebelo de Sousa,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

I understand that you are having 715-123420: An error occurred. Please reach out to support for additional assistance.

The failure pattern is not consistent with a normal region, quota, or RBAC problem. Sweden Central is a supported Foundry region, GPT-5.4 is an official Foundry/Azure OpenAI model family, and Microsoft’s support model for Developer/Priority Customer Support - PCS allows Azure engineers to create a support ticket on your behalf for complex cases. The right action is not more portal troubleshooting. But Microsoft internal escalation using your failed deployment correlation IDs and subscription/resource identifiers, sent through PCS/private message so the backend team can review and remove the subscription-level hold if present. Until Microsoft completes that review, there is no customer-side fix that can reliably restore new GPT-5.4 deployments. - https://learn.microsoft.com/en-us/azure/foundry/reference/region-support, https://learn.microsoft.com/en-us/azure/azure-portal/supportability/how-to-create-azure-support-request

If this is not resolve to time, comment escalate so that I can help with that or use PCS.

I hope this is helpful! Do not hesitate to let me know if you have any other questions, steps or clarifications.

I was contacted via DM. I provided the details. I'm still waiting on any sort of feedback or resolution. What exactly are the next steps here?

Hi @Ricardo Jorge Rebelo de Sousa

So sorry for this kind of issue.

Please, endeavor to follow instruction in my answer if private DM doesn't work for you.

Cheers

What exactly are the instructions on your answer? If it is re. escalation, then yes, please do. I need it fixed/resolved/telling me what the issue is - whatever path is easier.

Are you on paid support?

Do you contact PCS?

I am not. I was hoping I wouldn't need to be on paid support to at least understand the cause of an error. Wasn't the whole point of your feedback (and that of others) that you'd help escalate as needed?

I now upgraded and opened a ticket. Hoping for a fast resolution of this ongoing issue.
