Common Causes

  • API key is invalid, expired, or revoked
  • Wrong API key for the organization or project
  • Environment variable not set or set incorrectly
  • Billing issue — account suspended due to payment failure
  • Meta Llama's authentication servers are experiencing issues

✓ How to Fix It

  1. Verify your API key is correct — regenerate it from Meta Llama's dashboard if needed
  2. Check that the key is assigned to the right organization/project
  3. Ensure the environment variable (OPENAI_API_KEY, ANTHROPIC_API_KEY, etc.) is properly set
  4. Check your billing status — overdue payments can disable keys
  5. If using OAuth/SSO, try logging out and back in
  6. Check this page — if others report auth issues, it may be a Meta Llama-wide problem
