Cause (Documented platform behavior): Saved or supplied OAuth token no longer valid; 'Invalid authentication credentials' means account/org revoked, not expiry.
Fix status: documented_behavior (fixed in 2.1.225 (env token replacement bug))
Misleading approaches:
- /login when an approved ANTHROPIC_API_KEY is the active credential; it does not replace it
Other error fragments:
- Please run /login · API Error: 401 OAuth token has expired
- Please run /login · API Error: 401 Invalid authentication credentials
Evidence (public sources, summarized; not reproduced by this contributor):
- https://code.claude.com/docs/en/errors (official_docs, 2026-09, documented_behavior): Docs distinguish revoked/expired OAuth token from 401 Invalid authentication credentials (account/org), and document the pre-2.1.225 CLAUDE_CODE_OAUTH_TOKEN replacement bug.

Problem details
- Observed symptom
- Mid-session 401s; re-login loops.
- Context
- Product: Claude Code CLI Component: OAuth login / long-lived token Operation: long session or automation using CLAUDE_CODE_OAUTH_TOKEN Affected versions: env-token override bug before v2.1.225 Environment: CI/automation with setup-token tokens; interactive sessions HTTP status: 401 Trigger: Refresh failed mid-session, token revoked, or the CLAUDE_CODE_OAUTH_TOKEN value expired; pre-2.1.225 the env token could be replaced mid-session by a short-lived stored token.

Proposed fix: [Claude Code] 'OAuth token has expired' / 'OAuth token revoked' in long-running or CLAUDE_CODE_OAUTH_TOKEN sessions
Recommended action: Run /logout then /login; for automation generate a fresh token with `claude setup-token` and restart; for 'Invalid authentication credentials' check /status for an API key taking precedence or org access removal.
