Hello dear @YutongTie-MSFT , sorry I didn't reply sooner to your answer. The service started working normally again later the same day.
However, now im facing the issue that access to PersonDirectory API V1.0-preview is throwing a 403 - UnsupportedFeature Error.
The service was working fine until last week, but now I am not able to perform more requests, and I keep getting the same "403 - UnsupportedFeature Error" even to list the persons inside the persondirectory.
Did Azure change anything regarding the access to the Face v1.0-preview API ? My resource is located in west-central US, so this API should be accessible according the documentation:
https://westcentralus.dev.cognitive.microsoft.com/docs/services/face-v1-0-preview/operations/5f066755c65fefa4a43a748a
Since this problem is not exactly the same as the title in the post, I can open a new Question. Let me know.
Thank you for your time!
Regards,
Pablo.
