Bug Description

Persistent API 500 Internal Server Error affecting all chats and terminals simultaneously.

API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id":"req_011CY14wgpph7Qvc838Fmtvm"}

Environment

  • Platform: macOS
  • Subscription: Claude Max ($200/month)
  • Claude Code version: 2.1.38 (latest)
  • Issue started: February 10, 2026, ~15:00 CET

Behavior

  • Error occurs on ALL chats/terminals simultaneously
  • Was working seconds before the error started
  • Restarting terminal doesn't fix it
  • Affects all conversations, not just one
  • Updated Claude Code to latest version (2.1.38) — issue persists

Request IDs

  • req_011CY14wgpph7Qvc838Fmtvm

Additional Context

Multiple terminals with different conversations all failed at the same time. A clean update to the latest CLI version did not resolve the issue. This appears to be a server-side issue affecting all API calls for the account simultaneously.

Hi folks, thanks for reporting this. These 500 errors were caused by transient API outages on the Anthropic side — not a bug in Claude Code itself. The API is currently healthy, so I'm closing this out. If you're still experiencing 500 errors, you can check the API status at https://status.anthropic.com, and if the issue persists while the status page is green, please open a new issue with your request ID and we'll investigate.
