522 Connection Timed Out
A Cloudflare error meaning the connection to the origin server timed out before it was established.
What it means
HTTP 522 is a non-standard Cloudflare status returned when the TCP connection between Cloudflare and the origin could not be set up within the allowed time. Unlike 521, where the origin actively refuses, here the origin simply never completes the handshake.
When it happens
It happens when the origin is overloaded and too slow to accept connections, when a firewall silently drops Cloudflare's packets, when the origin IP in DNS is wrong, or when network routing between Cloudflare and the origin is broken.
How to fix it
- Check that the origin is not overloaded and can accept new connections promptly.
- Confirm the firewall allows Cloudflare's IP ranges instead of silently dropping them.
- Verify the DNS record points to the correct, reachable origin IP.
- Investigate network or routing issues between Cloudflare and the origin.
SEO impact
Damaging if sustained. A timeout reads as a server failure to crawlers, blocking indexing and reducing crawl rate if it recurs.
