What Are the Causes Of 502 Bad Gateway Error?

HTTP errors, while very common, are hard to figure out the reasons for. This is the case because there are quite a few reasons a server can experience this issue. The main three are:

  • The domain name of the page you’re trying to access is either not resolving to the correct IP, or it’s not resolving to any IP. This problem can be caused by a problem while resolving the hostname to an IP address. 
  • The server may not be reachable at that moment. Maybe the server is going through maintenance, or there’s a bigger influx of users than usual. These can cause the servers to be down.
  • A firewall could be blocking the communication between the frontend server and the backend server. If their Content-Management-System (CMS) security measures are overactive, they could be blocking requests from their systems.
