How we fix Cloudflare error 522?
When our customers approach us with this error, we check for the possible causes and fix them. Let’s see a few instances here.
1. Unblock the Cloudflare IP
One of the main reasons for the connection timeout error is, blocking the Cloudflare’s IP by the firewall or other filtering applications.
Sometimes, the IP will be blocked in the .
htaccess file
too. Therefore, our
Support Engineers
make sure to whitelist the Cloudflare IP addresses.
2. Conflict with WordPress plugins
Sometimes, WordPress plugins may be a threat to the server and create more queries than required. Therefore, the corresponding database gets overwhelmed and causes a high load on the server.
So, we check which plugin is affecting the speed of the connection. Also, we remove the plugin and suggest a suitable plugin with the same features.
3. Firewall in cPanel
cPanel is commonly used among Internet owners as a popular control panel. In cPanel, we can set up the number of connections that can access the server. Therefore, if it is set up wrongly, the Cloudflare 522 error shows up.
Then, our
Support Engineers
check the firewall settings and modify it to limit the rate of connections.
4. Overloaded or offline origin web server
Too many requests to a server may cause a high server load and result in a server crash. This can lead to a connection timeout error when anyone is trying to access the resources.
Hence, we check the server load and take appropriate measures.
5. Mismatch in DNS settings
Similarly, improper DNS settings in a server can end up in error. If the IP forwarding in DNS settings is not correct, we correct it to fix the error.
6. Enable
keepalive
To maintain an established connection Cloudflare uses
keepalive
header. If someone has disabled this in the configuration, it can lead to a connection timeout error. In such cases, we check such settings and make necessary changes.
