Azure resolved the issue, models are back to normal: https://azure.status.microsoft/en-us/status

Microsoft Azure is currently experiencing a downtime across its OpenAI Services in the Sweden Central region: https://azure.status.microsoft/en-us/status

This is affecting users who configured their own OpenAI models hosted in the Sweden Central region.

As a workaround, we recommend deploying the models in a different (EU) region.

If you use the models provided by Langdock, this does not affect you.
