Hi @BHARGAV JOSHI,
Thank you for reaching out to Microsoft Q&A forum!
Based on the error message you provided, it seems that the authentication token is missing or invalid. Here are a few things you can recheck to resolve the issue:
- Recheck if the subscription key is still valid and has not expired.
- Verify if the API endpoint URL is correct.
- Check if you have the necessary permissions to access the resource.
- Might this issue would be intermittent, it could be due to a temporary network or server issue. In this case, you can try again later to see if the issue has been resolved.
- Try Clear browser cache and cookies and also try using a different browser.
Let us know if the above information helps. Thank you.
