[BUG] 401 Invalid bearer token on every request - Pro plan not recognized - Nigeria

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?

Login always succeeds but every prompt returns 401. Confirmed working on another PC with same account. Complete reinstall + full wipe of all claude files makes no difference. No ANTHROPIC_API_KEY set anywhere. billingType shows stripe_subscription in config but UI shows "API Usage Billing". Location: Lagos, Nigeria. Account: [atechwebsitesolutions@gmail.com](mailto:atechwebsitesolutions@gmail.com). This requires backend investigation — the OAuth tokens being issued for my account are being rejected server-side.

What Should Happen?

It should be showing me claude pro or claude api instead of api usage billing since I am not usng api usage billing?
