How to Fix Cloudflare Error 522 in 2024?
Error 522 is typically caused by a connectivity issue between the Cloudflare server and the hosting server. Before you try to fix CloudFlare error 522, first check a few things:
- Check your origin server’s status to ensure that it is online and accessible.
- Verify Cloudflare DNS proxy status to make sure they are correct.
- Check Cloudflare firewall rules and network settings to ensure that they are not blocking the connection between Cloudflare and the origin server.
- Check Cloudflare SSL certificate encryption mode.
- Check if there is any WordPress plugin on your hosting server that might be blocking the connection.
- If possible, try to access the website via a different network or device to rule out any issues with your current connection.
If these steps do not resolve the issue, you can follow the below guide for further assistance:
1: Unblock the Cloudflare IP: Sometimes, Your hosting provider blocks 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 plugins 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 monitor the profile or activity of each of the plugins. After using this plugin, you can easily detect plug-ins that are causing server load issues.
3: Use Cache Plugin: WordPress cache plugins 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 CloudWays provide their own cache plugin for ultimate performance. You can also try the WP Rocket or FlyingPress plugin to minimize your website file size and reduce database requests or queries.
4: Use the lightweight theme: The WordPress theme also affects your website performance. I’m using currently using the GeneratePress WordPress theme. You can use Astra or GeneratePress to optimize your website, both are 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.
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 errors.
