One of the most frustrating aspects of running a website is having to troubleshoot an error when you don’t know why it’s happening. Some issues, such as the 502 bad gateway error, have many potential causes. This means you may need to try multiple solutions before you land on the right one. In this article, we’ll be fixing the Bad Gateway Error in WordPress websites.
What is a 502 Bad Gateway Error?
A 502 bad gateway error is triggered when your WordPress hosting server gets an invalid response for the requested page. Bad gateway error is one of the common WordPress errors that you may encounter on your site. It can be by a number of reasons and depending on your server the error message may also differ in looks slightly.
When you visit a website your browser sends a request to the hosting server. The hosting server then finds the page and sends it back to your browser with the status code. As a result, you wouldn’t see this status code. However, in case of an error, the status code is displayed with an error message. Examples of such errors include 404 not found, 503 services unavailable, 403 forbidden error, and more.
The most common reason for a 502 bad gateway error is when your request takes too long for the server to respond. This delay can be a temporary glitch caused by high traffic. It could also be a glitch by poorly WordPress tools or plugin. Last but not least, it can also happen due to a server misconfiguration.
Fixing The Error
A 502 bad gateway error is typically a problem with the network/server, however, it can also be a client-side issue. So we’ll dive into a little of both. Check out these common causes and ways to fix the 502 bad gateway error to and get back up and running. Don’t just manage your website errors. Reduce the risk of them ever happening at all.
Browser Cache To Fix Bad Gateway Error
Whenever you encounter issues like these it can be good to clear your browser cache. Below are instructions on how to do it in various browsers.
Test on Another Device
If none of the above solutions fixed the 502 bad gateway error, test the connection on another computer or a mobile device, preferably connected to a different network. This is the final step that will rule out whether the error is related to your machine or if the problem lies elsewhere.
The primary reason we typically see a 502 bad gateway error is due to an issue with the web host. Sometimes a query, script, or request will take too long and so it is canceled or killed by the server. A lot of hosts, especially shared hosts implement what they call a “kill script.” Basically what this does is it will terminate a request after a certain period of time so that it doesn’t take a site down or impact other users. If you do a Twitter search for “bad gateway” you can see thousands of tweets happening every day alerting their hosting company of the problem.
Re-loads To Fix Bad Gateway Error
One of the easiest and first things you should try when encountering a 502 bad gateway error is to simply wait a minute or so and reload the page (F5 or Ctrl + F5). It could be that the host or server is simply over and the site will come right back. While you’re waiting, you could also quickly try a different browser to rule that out as an issue.
Another thing you can do is to paste the website into downforeveryoneorjustme.com. This website will tell you if the site is down or if it’s a problem on your side.
A 502 gateway error could also be because of a DNS issue, such as the domain is not resolving to the correct IP. If you have just migrated your WordPress site to a new host, is it important to wait for things to fully propagate, which can take up to 24 hours in some cases? This depends upon the TTL value of your DNS records.
