Claude Code v2.1.300 ·

Cloud sessions get their sign-in and organization in a different way

Cloud session setup now looks up your sign-in token and organization through shared code, and the missing sign-in message may read differently

Unclear It is not clear whether ways of signing in other than claude.ai now work for cloud sessions.

What

Cloud sessions run Claude Code on remote machines. Three steps for them now look up your access token and your organization through shared code instead of reading your claude.ai sign-in directly:

  • fetching remote environments
  • creating cloud environments
  • listing self-hosted pools (groups of your own machines that run sessions)

When no token is found, the error is now built by shared code rather than using the fixed message that told you to run claude auth login. A new error also covers failing to find your organization.

Why

If you are not signed in, the message you see for cloud sessions may be worded differently from before.
