Thanks for posting your question in the Microsoft Q&A forum.

I believe that following one of these steps can help resolve the issue:

1. Enable detailed logging for API calls to identify any issues with the URI or request parameters.
2. Verify DNS resolution to ensure the correct mapping of the API hostname to its IP address.
3. Check for any API access limitations, such as IP-based restrictions, and address them accordingly.
