Resolving Connection Timed Out: Your Comprehensive Guide to Fixing the Cloudflare Error 522

The digital landscape today relies heavily on seamless online experiences, making website performance a critical factor. However, even with advanced content delivery networks (CDNs) like Cloudflare, occasional hiccups can disrupt user experiences. One common hiccup is Cloudflare Error 522: Connection timed out.

In this guide, we'll dive into this error, explore its causes, and equip you with three proven methods to swiftly resolve it.

Understanding the Root Causes of Cloudflare Error 522

Cloudflare Error 522 is more than just an inconvenience; it's an HTTP status code that affects the connection between users and your website's origin server. This error occurs when the server fails to respond within a specific time frame, and it's important to note that it's not caused by Cloudflare itself. Rather, it's usually due to factors on the server side.

Common Reasons Behind Error 522

  • A. Server Overload
    High traffic volume overwhelms the server's ability to respond promptly.
  • B. Firewall Blocking Cloudflare Requests
    Certain web hosting providers' firewalls may block Cloudflare IP addresses.
  • C. IP Address Mismatch
    Inconsistent IP addresses between your domain's DNS and Cloudflare settings.
  • D. Disabled KeepAlive
    The absence of the KeepAlive header can hinder the server's responsiveness.

Method 1: Checking Server Connection and Memory

Before delving into complex solutions, start by assessing your server's health. Is it coping with the incoming requests? If you're on shared hosting, this is particularly relevant. Use tools like the Packet Internet Groper (PING) command (Linux) or Traceroute (Windows) to check your server's connectivity and performance. Remember, optimal resource usage is key to preventing this error.

Method 2: Reviewing Cloudflare DNS Settings

  • A. DNS Records Significance
    DNS records, including the Address Record (A Record), are crucial for IP address association.
  • B. Steps for A Record Match
    Use Cloudflare's DNS Zone Editor to ensure consistency in IP addresses.
  • C. Cloudflare Adjustment
    Adjust Cloudflare's A Records to match your hosting server's IP addresses.
  • D. Enhancing Security
    Set Cloudflare's encryption mode to "Full" for added protection.

Method 3: Configuring Server Settings

  • A. Enabling KeepAlive Header
    KeepAlive maintains stable connections between Cloudflare and the server.
       - Instructions for adding the KeepAlive code to .htaccess or nginx.conf files.
  • B. Allowing Cloudflare IPs
    Ensure firewall compatibility by permitting Cloudflare IPs in your server's settings.
       - Use IP Manager (Hostinger) or .htaccess for manual IP routing.
  • C. Temporarily Disabling Cloudflare
    As a last resort, consider temporarily disabling Cloudflare to troubleshoot.


In the dynamic realm of web hosting, Cloudflare Error 522 is a familiar challenge, but it's certainly not insurmountable. With the three expert methods discussed in this guide, you're well-equipped to tackle this error head-on.

Remember, maintaining optimal server resources, aligning DNS settings, and configuring server attributes can significantly enhance your website's performance.
