Solution to fix Cloudfare Error Code 522

  • Disable interfering Plug-ins

Sometime, specific plug-ins that create a variety of queries more than the required and an increase in the corresponding database will generate a high load on the server.

To get rid of this problem, you need to install the Plug-in performance profiler and it helps to detect which plugins are mischievous with the overloaded queries in the database. Once the issues are identified successfully, you can uninstall the interfering plugins and check if the problem is fixed.

  • Enable Cache Plug-in

The cache is that part of the memory that stores the data from the website you visit frequently. Therefore you can reduce the server load by decreasing the queries to the corresponding database. You can easily improve the connection speed of the server with the help of the cache plugin. Use the WP Super Cache plugin on a shared hosting service.

  • Manage Configurations

By managing, the configuration setting of the server can cause this error 522 to disappear but this is a lengthy task. First, you need to remove the domain on Cloudflare, then install the cPanel again and add the domain name. This kind of process will help to remove the bug.

  • Image optimization

The process of compressing the image size for better optimization will help to reduce the server load and decrease bandwidth consumption. Consequently, it will increase website speed.

  • Contact Hosting Provider

You can check with your hosting provider to identify any blocking attributes to Cloudflare systems. Contacting your hosting provider would ensure that your server does not block any of the Cloudflare’s IP’s.

  • Implement Lazy load plug-ins          

You can reduce the usage of image bandwidth to an extent with the help of these plug-ins and thereby enhance the performance on a large scale.

Wrapping up:

Make sure your website responds to Cloudflare queries within 60s by compressing your image, activate the ‘keepalive’ message, and optimize your database. Thereby you can reduce your bandwidth consumption.
