What
A cloud session is a Claude Code session running on a remote computer rather than your own. When sending a file from one fails with a 401 error (a "not authorised" reply), Claude Code now adds an explanation to the error. It says the cloud environment's sign-in has expired and tells you to wait about five minutes before trying again.
Why
You get a cause and a next step instead of a bare error code.
