The main reasons for this Error 522 problem are: Cloudflare IP addresses are rate limited or blocked in .htaccess, iptables, or firewalls. Confirm your hosting provider whitelists Cloudflare IP addresses. And some times an overloaded or offline origin web server drops incoming requests.
Cloudflare is the most used CDN right now and You can face error 5XX with both premium & free users. Below are the quick solutions to your problem.
How to Solve Error 522: Connection timed out
1: Unblock the Cloudflare IP: Sometimes, Your hosting provider blocks the Cloudflare’s IP in the firewall, httacess, and iptables file. Now, contact your hosting support team and ask them to whitelist the Cloudflare IP addresses. You can also unblock Cloudflare IP from your website file manager.
2: Disable WordPress plugins: WordPress plugin that supplies database queries to your server often. Make your hosting server free enough space to serve Cloudflare CDN. You can try the P3 (Plugin Performance Profiler) plugin to monitoring the profile or activity of each of the plugin. After using this plugin, you can easily detect plug-ins that are causing server load issues.
3: Use Cache Plugin: WordPress caching plug-ins are there to minimize the number of database requests or queries issued to the server per visit. Using caching plug-ins can greatly decrease the number of queries supplied to your hosting server. It does reduce the chances of HTTP error 522.
Most of the hosting providers like SiteGround, CloudWays are provider their own cache plugin for ultimate performance. You can also try free WP Fastest Cache or w3 total cache plugin to minimize your website files size and reduce database requests or queries. I’ve been using the premium WP Rocket cache plugin on my all websites for about 2 years.
4: Use the light-weight theme: WordPress theme also affects your website performance. I’m using currently using the GeneratePress WordPress theme. GeneratePress is one of the most lightweight and fastest themes in the market. In fact, the entire theme is only 30kb when installed. While the average WordPress theme is over 1MB. The core GeneratePress theme is 100% free. Download my website theme.
5: Use Different CDN: Currently, most of the hosting providers offer their own CDN or Cloudflare CDN integrations on the hosting server (i.e: SiteGround, Bluehost, A2 hosting). If you choose these types of hosting, then Cloudflare CDN already optimizes for your website and you never face any Cloudflare 522 error.
I’m using WPX hosting to host this website & they offer WPX CDN for free. All you have to do change your hosting provider to WPX hosting, they offer free site migrations with premium WPX CDN for free. Try WPX Hosting CDN now.
