Authentication Failure: Persistent Offline State After Login

Bug Description
When I run Claude Code and login (using /login, then authorizing in a browser) and then submit a prompt Claude Code says it is offline, and I keep getting errors like "API Error (Request timed out.) · Retrying in 1 seconds… (attempt 1/10)". There is no connectivity problem as submitting prompts to Claude form the same machine (this machine) works perfectly.

I run /logout to sign out
Close Claude Code entirely
Restart with claude and complete authentication again

This doesn't work, so I clean stored authentication with:
rm -rf ~/.config/claude-code/auth.json

I get the same behavior.

❯ claude doctor
