Error Code 522 Cloudflare: Meaning & Fix
Cloudflare Error 522 indicates a connection timeout between Cloudflare and your origin web server. It means that Cloudflare established a TCP connection with the server, but the server failed to respond. Read on to learn about possible error code fixes.
What causes the Cloudflare error 522?
This error indicates issues with the origin web server being overloaded, having insufficient resources, experiencing network connectivity problems, or having firewall configurations that block Cloudflare's requests. Unlike other Cloudflare errors that indicate problems on Cloudflare's end, error 522 specifically points to an issue with the origin web server's ability to provide a timely response (usually 100 seconds).
How proxies can help handle Cloudflare error 522?
Traffic distribution
Proxies can distribute traffic across multiple origin web servers, preventing any single origin web server from becoming overwhelmed. If a server limits connections from an IP address, using rotating proxies gives you a different IP address with each HTTP request. The best proxy providers usually offer various types of rotating proxies, such as residential and mobile proxies.
Improved connection stability
A well-configured proxy can provide a more stable connection to your origin web server. Proxies can establish connections through different network routes, avoiding congested or problematic paths that might be causing timeouts.
Place a reverse proxy between Cloudflare and your origin web server.
Change the connection protocol from HTTP to HTTPS and ensure a valid SSL certificate.
Whitelist Cloudflare IPs on your system.
Update Cloudflare DNS settings to point to the proxy server instead of directly to an origin web server.
Geographic optimization
Proxies hide an actual IP address and geographic location, letting the origin web server see you as a different user with each browsing session. Using proxies in locations closer to your origin web server can reduce latency and help prevent timeouts. If your origin web server blocks traffic from certain regions where Cloudflare's data centers are located, a proxy can route traffic through allowed regions.
