How to Troubleshoot Cloudflare Errors
Every Cloudflare error page shows a Ray ID and tells you whether the browser, Cloudflare, or the origin host is failing. To test the origin directly while keeping the correct hostname, bypass Cloudflare with curl:
# Replace 203.0.113.10 with your origin server's IP
curl -svo /dev/null --resolve example.com:443:203.0.113.10 https://example.com/If this request fails or is slow, the problem is on the origin, not at Cloudflare. Also make sure your firewall, security plugins, and rate limiters allow Cloudflare's IP ranges.
