General

What steps will reproduce the bug?

1. Attempt to authenticate using invalid, expired, or missing credentials.
2. Make an API request that triggers authentication.
3. Observe that a 401 error is returned.
4. Application should handle this by notifying the user and prompting for re-authentication or providing clear feedback.

What is the expected behavior?

User is prompted to re-authenticate, error message is clear, and application recovers gracefully.

What do you see instead?

User is left with a generic error or the application becomes unresponsive after a 401 error.
