What's Wrong?

When connected to Claude Code via a remote SSH session, the session hangs / stops responding after asking only 2-3 questions in a row. It needs to be restarted to continue working.

What Should Happen?

The session should remain responsive for extended use over SSH, without hanging after just a few exchanges.
