What
When a session is refused, Claude Code now shows a message starting "Your session can't run on this machine" and names the cause. The causes are:
- A gateway or custom endpoint is in use
- Environment entries in the project change the model provider
- No model usable in auto mode is available
- An experimental-beta setting is turned off
- A compliance policy
A new check on CLAUDE_CODE_USER_DELEGATED_SESSION_DIRECT_API can lead to the reason that no allowed model is available.
Why
Sessions that run for someone else or on hosted machines now get a specific reason when they are turned away, instead of failing without one.
