These are temporary blocks on security side from backend automation. We collaborate with security to review and unblocks.

If you are having any support plan, you can share us details email, subscription id in private message to create support ticket and escalate to security team for review.

Error code 715-123420 is a generic Azure AI Foundry portal failure that the portal itself cannot resolve client-side. When this code appears while creating or editing a model or deployment, it indicates a backend or subscription-level issue that requires Azure support intervention.

Because this error explicitly instructs to contact support, the next step is to open an Azure support request and include:

The full error code and message: 715-123420: An error occurred. Please reach out to support for additional assistance.
The Azure subscription ID and the Foundry project/resource where the error occurs.
The operation being performed (for example, creating a deployment, editing an existing deployment, or training a model).
Timestamp and region of the operation.

Support can then inspect backend logs and fix issues such as:

Broken or partially created model/deployment records that block further operations (similar to the “Model Exists” condition described for Azure Document Intelligence models, which also requires backend cleanup by support).
Subscription, quota, or regional constraints that are not surfaced clearly in the portal.

If the issue is blocking production work and no obvious quota or region error is shown, contacting support is the only supported resolution path.
