What's Wrong?

Git push operations fail with 504 Gateway Timeout errors when using Claude Code webapp. All push attempts result in connection failures to the local Git proxy service, preventing any commits from being synced to the remote GitHub repository. The error persists across multiple retry attempts and the local proxy port number changes between attempts (26174 → 36877 → 63150), suggesting the service may be restarting but continues to fail.

This completely blocks the ability to push changes from the Claude Code webapp, and since there's no terminal access in the browser environment, there's no workaround available. The stop hook configured in the repository fires continuously because it detects unpushed commits, creating an infinite loop that interrupts the workflow.

What Should Happen?

Git push operations should succeed when executed from the Claude Code webapp, pushing local commits to the remote GitHub repository.

Additional Information

Timing: Issue began afternoon 11-18-25 Reproducibility: 100% - every push attempt fails Workaround: None available from webapp; would require external Git client access Service monitoring: Anthropic status page incorrectly shows all services operational Port behavior: Localhost proxy port changes between attempts (26174 → 36877 → 63150), suggesting service restarts but continued failure Stop hook: User has a git pre-stop hook that checks for unpushed commits, creating an infinite loop when push fails
