Thank you for your post and I apologize for the delayed response!
Error Message:
Access has been blocked by Conditional Access policies. The access policy does not allow token issuance.
Based off the error message that you're receiving - this indicates that the access policy does not allow token issuance. This can happen when a user or application tries to access a resource that is protected by a Conditional Access policy, but the policy conditions aren't met.
To troubleshoot or resolve this issue, you can:
- Review the error message that appears. For problems signing in when using a web browser, the error page itself has detailed information. This information alone may describe what the problem is and that may suggest a solution.
- Review your Azure AD sign-in logs to see which CA policy / policies were applied and why.
If you're still having issues even after reviewing your error details and sign-in logs, please let me know.
