[BUG] OAuth token expiration causing repeated 401 errors despite re-authentication

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

• 401 authentication_error with "OAuth token has expired"
• Required 4 login attempts to get past "auth failed"
• Error recurring even after successful re-authentication
• Request ID: req_011CXNgZ7zZJY834jK17vSWU

This will help the team track and fix the token refresh/persistence issue
you're experiencing.

API Error: 401 {"type":"error","error":{"type":"authentication_error","message":"OAuth token has expired. 
Please obtain a new token or refresh your existing token."},"request_id":"req_011CXNgZ7zZJY834jK17vSWU"}

What Should Happen?

it should not have this error :)
