Cloudflare is one of the best CDNs on the market.
The most annoying error you encounter when using Cloudflare is error 522.
This error occurs in both the free and pro version of Cloudflare. However, here Cloudflare is not the game player. Error codes starting with “5” are server-side errors. You can refer to the list of HTTP status codes for more information.
What is causing this 522 error?
As you may know, Cloudflare is one of the best CDNs out there, so resource requests are blazingly fast. It quickly demands resources from your server.
If your server fails to serve Cloudflare over time, the 522 error appears.
From there, you can notice that the real problem is with your server but not with Cloudflare. Most of the time, this error occurs in the case of shared hosting. Because resources are shared.
When Cloudflare does not get the resources for its request within the timeout period, error 522 appears.
Why is your server not responding to Cloudflare requests?
Your server will be busy responding to other database queries and requests from other plugins.
What is the solution?
How do I resolve Cloudflare error 522?
Ditch hyperactive plugins
Ditch the plugin or module that often provides database queries to your server. Make your server fast enough to serve Cloudflare.
Find out which of your plugins is slowing the site down. According to the Pareto principle, “about 80% of the effects come from 20% of the causes”. 80% of the time, the 522 error occurs due to faulty plugins, polling your server database more often.
Spotting the hyperactive plugin should be the first thing to do in this case.
To monitor the profile or activity of each of the plugins, you may need to install the P3 (Plugin Performance Profiler). While installing this plugin, it monitors all plugin activity silently. Including the number of database queries it makes and monitors server load issues caused by installed plugins.
It also displays the impact caused by plugins on page speed and others. He answers, what is the number of SQL queries per visit?
By using this plugin, you can easily notice which plugins are causing server load issues.
Use caching plugins
Caching plugins are there to minimize the number of database queries or server requests per visit. Most commonly used images and resources are cached in visitors’ browsers. Thus, the page rendering is faster the next time they visit your blog.
This allows your page to load at supersonic speed for returning visitors.
Using caching plugins can dramatically reduce the number of requests delivered to your server. It reduces the risk of an HTTP 522 error.
The best caching plugin for WordPress is W3 Total Cache. However, it is unfortunate that it causes server load issues in shared hosting. So I recommend WP Super Cache if you are using a shared hosting service.
Other tips for avoiding 522 errors on Cloudflare
- Minimize the use of plugins, especially visitor tracking plugins.
- Look for minimalist themes.
- Take a look at the Suggestions and Page Speed Score.
- Consider upgrading to a higher-quality dedicated server if you are having a lot of server issues.
Despite all these measures, if you are unable to get rid of the 522 error, I suggest you go to your hosting service provider for further assistance.
The surefire formula for overcoming this error is to reduce database queries on every visit.
