We get an Internal Server Error on Azure Cognitive services

Question

Since this morning we run into InternalServerError on Azure AI Vision Text searches. We use model 2023-04-15 for +1 year now, but stopped working this morning. The legacy model version 2022-04-11 does work but is not suitable for us.

We see no outage reported on Azure status, but are unable to resolve it ourselves.

Hello Johan Coens,

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

I understand that you are getting an Internal Server Error on Azure Cognitive services.

To resolve that, execute the below steps in order:

1. Switch your Vision endpoint to a healthy region (e.g., West Europe/East US). - https://learn.microsoft.com/en-us/answers/questions/2115918/quickstart-optical-character-recognition-%28ocr%29-int
2. Keep Read v3.2 with model-version=2022-04-30 (documented GA) on /vision/v3.2/read/analyze. Do not use 2023-02-01-preview for Read v3.2—it’s not in the official list. - https://learn.microsoft.com/en-us/azure/ai-services/computer-vision/how-to/call-read-api
3. Add 3 retries (exp backoff), plus a circuit breaker to stay on the secondary region while the primary is degraded. - https://learn.microsoft.com/en-us/answers/questions/5747009/azure-openai-doesnt-work-region-sweden-central
4. Log request IDs (x-ms-request-id, apim-request-id) and open a Severity A ticket with exact timestamps and comparison data (legacy/other region). - https://learn.microsoft.com/en-us/answers/questions/1497324/internal-server-error-when-calling-cognitive-servi, https://learn.microsoft.com/en-us/answers/questions/5742974/we-are-encountering-an-internalservererror-%28http-5
5. Enable Service/Resource Health alerts to get real‑time notifications and model lifecycle notices for proactive changes. - https://learn.microsoft.com/en-us/azure/ai-foundry/openai/concepts/model-retirements?view=foundry-classic

This plan above will restore service within the hour and it align strictly with current Microsoft documentation and incident reports.

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