Hello @Byungho Lee ,
Welcome to Microsoft Q&A .Thank you for reaching out to us.
Thank you for sharing the details regarding the 715‑123420 error observed during model deployment.
The 715‑123420 error is identified as a platform-level validation block rather than a configuration or quota issue.
This validation is performed during the deployment stage and may trigger when backend systems detect conditions requiring additional review .
As a result:
- Deployment fails immediately during validation
- The error message appears generic without specific details
- Other models or resources may continue to function normally
This explains scenarios where certain models deploy successfully while others are blocked under the same setup.
Although the issue is not caused by configuration, the following checks help confirm readiness:
- Model availability by region - Model availability varies across regions
- Quota and capacity validation-Quotas are applied per subscription,region and model
- Deployment consistency checks
- Ensure no stuck or duplicate deployment names
- Retry with a fresh deployment if needed
These checks confirm that no standard blockers (quota, region, or RBAC) are contributing to the issue.
While the validation is being reviewed, the following approaches may help continue progress:
- Use alternate models that are successfully deploying
- Attempt deployment in:
- A different region (where supported)
- A different deployment type (Standard / Global Standard)
- Retry deployment after some time (in case of transient backend behavior) Please note that if the validation block is tied to backend controls, these workarounds may not consistently bypass the issue.
