Like many other error pages on the world wide web, 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.
What causes the Cloudflare error?
Contrary to what one would initially suspect, the reason for the 522 error occurring is not due to Cloudflare malfunctioning but rather to a server-side problem.
