Cloudflare Error 522 - How to Avoid?

When you encounter Error 522, it signifies that Cloudflare is operational and able to send requests to the server, but the server is not responding in a timely manner. Unlike Error 524, which indicates that the server is taking too long to respond, Error 522 suggests that the initial connection could not be established at all.

Causes of Error 522

Server Downtime: The server is down for maintenance or due to technical issues.
Network Issues: Problems in the network between Cloudflare and the server can prevent connection establishment.
Firewall Configurations: Improperly configured firewalls might block or restrict Cloudflare’s requests to the server.
Resource Constraints: Limited server resources can hinder its ability to accept new connections.

How to Address Error 522

Check Server Status: Ensure the server is up and running without maintenance or downtime issues.
Review Firewall Settings: Confirm that firewall configurations are not blocking requests from Cloudflare’s IP addresses.
Inspect Network Connectivity: Troubleshoot network issues between your server and Cloudflare.
Optimize Server Resources: Ensure the server has sufficient resources to handle incoming connections and is not overloaded.
