What is an error 522?

The 522 message is one of the HTTP status messages. While the preceding ‘5’ indicates a server error, the following ‘2’ indicates that the server error has occurred in conjunction with Cloudflare.

Code 522 stands for ‘Connection timed out’, which occurs whenever the TCP handshake between the web server and Cloudflare fails. This handshake – which is essential for establishing a connection – becomes necessary whenever the CDN service receives a user request that requires consultation with the server. Due to the high usage of Cloudflare, the 522 connection timed out error is one of the most common browser error messages.

The most common reasons for the connection timed-out message error 522:

  • Web server is offline: the HTTP error 522 is often displayed because the contacted web server is offline.
  • Overloading the original server: if too many requests are to be processed at the same time.
  • A firewall is blocking the request: the IP addresses of the performance service should be allowed by this service by default, however, sometimes addresses are accidentally or randomly blocked.
  • Incorrect DNS settings: many web hosts automatically assign new web addresses to the managed websites every so often and do not forward them to Cloudflare, the DNS setup sometimes uses an incorrect address.
  • Incorrect routing: IP routing, which regulates the path of the packets sent through the various networks involved, is an elementary part of the content delivery process. If there are discrepancies between the original server and Cloudflare, this results in a connection timed out message.
  • Keepalive messages are disabled on the server-side: Since most common web servers allow the keep alive entry by default, this is a relatively rare cause of the error and almost always has something to do with a configuration error on the webmaster’s part.
  • the most promising solutions for fixing the 522 error
  • Optimize server capacity
  • Check IP filtering
  • Customize DNS/IP settings
  • Activate the ‘keepalive’ message
  • Contact Cloudflare-Support

HTTP error 522 is only a server-side problem So if you just browse through the world wide web and encounter the 522 message when you visit a website, this is not due to a faulty internet connection or a faulty plugin.

However, this also means that you cannot solve the problem directly. To keep frustration to a minimum, it’s advisable to wait, visit the website later. Hopefully, the communication problem between Cloudflare and the webserver will have been fixed by. Then, the site will be displayed as normal.
