Introduction
Sometimes, when you visit your website, the 502 Bad Gateway error appears, which can be annoying. So, if you want to Fix 502 Bad Gateway Error, the instructions in today’s blog will help you do that.
First of all, let us bring you some fundamental information about this error. Whenever you access a website, the browser you are using will send a request to the WordPress hosting server. After that, the hosting server will find the page, then send it to your browser with a status code. However, you won’t see the status code. In some cases, because of errors such as 503 Service Unavailable, 404 not found, and much more, the status code will appear with the error message.
The 502 Bad Gateway error is one of the most common errors when you develop a WordPress website. This error is caused by many different factors. However, the most common reason is that the request you send is taking too long for the server to respond. This means the error may appear because of high traffic or a problem with the WordPress plugins or themes. Besides that, a server misconfiguration can cause this error.
So, what should you do to solve the problem? Let’s explore the 5 steps below.
Methods to Fix 502 Bad Gateway Error in WordPress
Reloading the website
Firstly, you may see the error when the site traffic is increasing or the server resources are low. In this case, don’t worry since the error will disappear automatically in a few minutes. Thus, all you need to do is reload the website. If the website returns to normal, you do not need to continue to the next steps. On the other hand, if this error still occurs frequently, then let’s continue to try the following steps.
Clearing the cache of the browser
Sometimes the error happens because the browser is loading the site from the cache. Therefore, to tackle the problem, you just need to clear the browser cache.
Let’s open the browser, then go to the three dots icon on the top right of the screen. After that, simply go to More Tools -> Clear Browsing Data to clear the site cache. After clearing, don’t forget to load your site again to check the result.
Besides that, if the error occurs because of the browser cache, you can also use another browser to get around the problem.
Disabling the CDN or Firewall
If the two steps above don’t work, the next step is to disable the CDN or firewall. If the error is fixed after disabling, you need to get in touch with your CDN service provider for support. When the problem is addressed completely, you can enable the CDN again.
Updating Themes/ Plugins for your WordPress site
You can try the fourth step if the error is still there. Now, you need to check your WordPress themes and plugins.
First of all, let’s deactivate all the plugins by using FTP. Then, open your front-end site and check if the error has been fixed. If yes, you need to activate the plugins one by one to find exactly which plugin causes the error. After that, simply search for an alternative plugin. You can also get in touch with the plugin author to ask about the issue.
If the error is not coming from plugins, you should check the WordPress theme. So, you need to switch your current theme through phpMyAdmin. Then, let’s use the default theme and access your site to check. If the error disappears, well done. If not, let’s move on to the last step.
Checking the Hosting Server
If the four steps above can’t help you tackle the problem, the error may come from your hosting server. Hence, you should contact your hosting provider for support. Don’t forget to tell them that you tried the 4 troubleshooting steps but they didn’t work. That way, the hosting provider can help you find a solution effectively.
