What's Wrong?

Describe the bug
Claude Code suddenly logged out on its own without any action from my side. After re-authenticating, it prompted me to select a subscription plan again, and then showed a "credit balance is too low" error — even though I'm on a Pro plan and rarely hit usage limits.

The issue resolved itself after doing a manual claude logout followed by claude login again without selecting any plan or adding API credits.

Steps to reproduce

1. Using Claude Code normally on a Pro plan
2. Claude Code suddenly logs out on its own (no action triggered)
3. Re-authenticate via claude login
4. After authorization completes, prompted to select a subscription plan
5. "Credit balance is too low" error appears
6. Workaround: run claude logout → claude login again → issue resolved

Expected behavior
Claude Code should maintain the authenticated session and recognize the active Pro plan without requiring re-selection or showing a credit error.

Actual behavior
Unexpected logout → re-auth triggers plan selection prompt → "credit balance is too low" error despite active Pro subscription.

Workaround
Running claude logout and claude login a second time (without selecting a plan or adding API credits) resolves the issue.

Environment

• Plan: Claude Pro
• Claude code

Additional context
This seems like a session token issue where re-authentication incorrectly routes to API/Console billing instead of the existing Pro plan credentials.
