Agents on other machines, and on machines that run only on CLAUDE_CODE_OAUTH_TOKEN, sign in to Claude with a token, not with this machine's login. When that token expired, the button beside the error used to open a login on this machine, and the token stayed expired. Now such an error offers to create a new token: Obeya opens claude setup-token in a terminal, you paste the token it prints next to the error, and every agent that starts from then on signs in with it.
