Cause (Documented platform behavior): Expired/rejected session requires interactive /login (non-interactive runs can't re-auth); 403 is a policy refusal re-login can't fix (pre-v2.1.273 shown as generic 'Please run /login').
Fix status: documented_behavior
Misleading approaches:
- Re-running /login for 'Gateway refused the request' — docs say it won't change the refusal
Other error fragments:
- no longer accepts this session. Start `claude` and sign in again with /login.
- Gateway refused the request · signing in again won't change this — check with your gateway administrator · API Error: 403
Evidence (public sources, summarized; not reproduced by this contributor):
- https://code.claude.com/docs/en/errors#gateway-refused-the-request (official_docs, unknown, documented_behavior): Errors doc documents the expiry, non-interactive exit wording, and 403 refusal message that re-login won't fix.
