What's Wrong?

When running Claude Code via SSH on a remote machine, session disconnects and requires re-login every ~30 minutes. Does not happen on the local machine.

What Should Happen?

Session should persist for the duration of an active working session without requiring re-authentication. Re-login should only be needed after extended inactivity or explicit logout.

Additional Information

Additional context:

• Only happens over SSH — local machine sessions persist normally
• Likely related to SSH session environment: missing token refresh mechanism, TTY differences, or environment variables not propagating correctly over SSH
• Auth method: Claude.ai login (not API key)
• Remote OS: macOS 25.2.0
