Cloudflare error 522: connection timed out
Cloudflare tried to open a TCP connection to your origin and got no answer in time. The origin is offline, overloaded, or silently dropping Cloudflare's packets.
Where it failed: the origin behind Cloudflare
What visitors see
Cloudflare's "Connection timed out" page with a Ray ID.
Usual causes
- The origin server is offline or overloaded.
- A firewall drops (rather than refuses) Cloudflare's traffic.
- The DNS record in Cloudflare points at an old or wrong IP address.
- The origin's network is down.
How to tell which one it is
- 522 is a timeout on connecting; 521 is a refused connection; 524 is a connection that worked but an answer that took over 100 seconds.
- Check the A record in Cloudflare's DNS tab is the origin's current IP.
What to do
- Confirm the origin is up and reachable from another network.
- Fix the DNS record if the IP changed (a new server, a new load balancer).
- Allow Cloudflare's IP ranges in the firewall; make sure it is not rate-limiting them.
