403

Likely cause

The origin/application itself denied this request.

What to do

  1. Check. First check Cloudflare's Security > Events log (if this site is Cloudflare-fronted) for a matching blocked request; if nothing matches there, check the application's own authorization/permission logic.
  2. Fix. If a Cloudflare rule matched, narrow it or add an allow rule for the legitimate traffic. If it's application-level, correct the permission/authorization check that's rejecting this request.
  3. Verify. Retry the request and confirm it's no longer rejected.
