Hi Amaury,
Thank you for posting in Microsoft MCM Q&A forum.
According to your description, it seems the problem is NOT a MCM problem. This issue is more related on Azure AI services, you may add the corresponding tag so that the experts who are familiar with that topic may help. You can also post a new thread in that forum to get better support.
Thanks for your understanding. Have a nice day!
Best regards,
Simon
