We visit many webpages, and from time to time, we can face frustrating errors such as the 502 Bad Gateway Error. In this article, we’ll provide you with the information to know what this error is and how to combat it.
What Is 502 Bad Gateway Error?
The HTTP stands for HyperText Transfer Protocol. We’ll straightforwardly explain this error. 502 Bad Gateway is a server error response. It means the backend server received an invalid response from the frontend server. The server received the information request but was unable to fulfill it. In the event of this happening, the page might display some recommended actions and the HTTP status code for this error.
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.
How to Fix 502 Bad Gateway Error
Unfortunately, most of the time, the solution to this error can only be implemented by the website’s host or developer. But all hope is not lost! Users can still try the following methods.
- Reloading the page. This sounds simple and overused, but frankly, a lot of times, this will be enough to solve the issue.
- If reloading the page didn’t work, you can try a hard refresh on your browser. You can perform this on windows by pressing “CTRL + Shift + R” and then on Macs pressing “Cmd + Shift + R.”
- One other reason could be your DNS. If you’re using the default DNS configuration, try switching to a different one. Google’s Public DNS (184.108.40.206, 220.127.116.11) is one of the most commonly used options.
- And then lastly, clearing your browser cache as well as deleting the cookies might help with the error.
