429

Likely cause

The origin/application's own rate limiting rejected this request.

What to do

  1. Check. Check Cloudflare's Security > Events log (if Cloudflare-fronted) for a matching Rate Limiting rule; if nothing matches, check the application's own rate-limiting configuration or middleware.
  2. Fix. Reduce request frequency to stay under the limit, or adjust the rate-limiting rule/configuration if it's set too aggressively for legitimate traffic.
  3. Verify. Wait for the rate-limit window to reset, then retry and confirm the request succeeds.
