This article will talk about Error 522 Connection timed out. But first, it is important to say that there are special services to monitor the online status of a site and assess site accessibility.

One of these services is the BAILRY service – a free regular (periodic) website accessibility check. This service also has a paid subscription for constant monitoring of site availability.

Error 522 occurs when a timeout occurs while waiting for a response from the web server.

Main reasons:

  • the web server is overloaded and did not respond to the request;
  • the web server has a security system that blocks requests from CloudFlare;
  • web server is unavailable;
  • incorrect IP address set in the DNS settings on CloudFlare (the request from CloudFlare was sent to a different IP);
  • problems with network routing between CloudFlare and the web server.

To resolve this issue, make sure your web server is active and accepting HTTP requests. Check if the DNS settings in your Personal Account on CloudFlare are correct.

Recommendations for fixing error 522

Contact your hosting provider to check the following common causes on your origin web server:

  • Most common reason: Cloudflare IP addresses are rate-limited or blocked in .htaccess, iptables, or firewalls. Confirm that your hosting provider allows Cloudflare IP addresses.
  • An overloaded or offline origin web server discards incoming requests.
  • Keepalives are disabled on the origin web server.
  • The source IP address in your Cloudflare DNS application does not match the IP address currently allocated to your source web server by your hosting provider.
  • Packets were dropped on your origin web server.

If none of the above leads to a solution, request the following information from your hosting provider or site administrator before contacting Cloudflare support:

  • MTR or trace from your web server to Cloudflare IP is the address that is normally connected to your web server before the problem occurs. Determine the connecting Cloudflare IP address recorded in the origin web server logs.
  • Details of the hosting provider’s investigation, such as relevant logs or conversations with the hosting provider.

Finally, it is important to note that the trust of clients and users in your website, as well as your position in search engines, directly depend on the availability of your resource (website) at any given time.

And you can control this availability using the BAILRY service – a unique software product that has no analogues on the market. To stay informed, sign up for a free regular (periodic) website accessibility check today!
