What is a 502 Bad Gateway Error?
Before we get started, let’s take a look at what a 502 Bad Gateway error actually is.
A 502 error Bad Gateway is an HTTP status code that means that one server on the internet received an invalid response from another server.
The 502 error Bad Gateway is often caused by a plugin or theme function. Other common causes include a corrupted .htaccess file and a misconfigured server.

Method 1: Reload the Page
The first thing you should do when you see a 502 error Bad Gateway is simply wait a few moments and then reload the page.
Sometimes, the error is just temporary and will go away if you try reloading the page. If the error persists, move on to the next method.

Method 4: Deactivate Your Plugins
If you’re still seeing a 502 error Bad Gateway, the next thing you should do is deactivate all of your WordPress plugins.
You can do this by logging into your WordPress site via FTP and then navigating to the /wp-content/plugins/ folder.
Once you’re in the plugins folder, rename the plugins folder to something like plugins_old.
After you’ve renamed the plugins folder, try accessing your WordPress site. If it loads without a 502 Bad Gateway error, then one of your plugins was causing the error.
To find out which plugin was causing the error, you can activate your plugins one at a time until the 502 Bad Gateway error reappears.
Once you’ve found the plugin that’s causing the error, you can either try to find an updated version of the plugin or contact the plugin developer for help.
If you’re still seeing a 502 error Bad Gateway after deactivating your plugins, move on to the next method.
Method 5: Deactivate Your Theme
If you’re still seeing a 502 error Bad Gateway, the next thing you should do is deactivate your WordPress theme.
You can do this by logging into your WordPress site via FTP and then navigating to the /wp-content/themes/ folder.
Once you’re in the themes folder, rename the folder for your active theme to something like theme_name_old.
After you’ve renamed the folder, try accessing your WordPress site. If it loads without a 502 error Bad Gateway, then your theme was causing the error.
To find out if your theme was causing the error, you can activate one of the default WordPress themes (like Twenty Seventeen) and then try accessing your WordPress site.
If the 502 Bad Gateway error reappears, then your theme is most likely the cause of the error. In this case, you can either try to find an updated version of the theme or contact the theme developer for help.
If you’re still seeing a 502 Bad Gateway error after deactivating your theme, move on to the next method.
Method 6: Check Your .htaccess File
If you’re still seeing a 502 error Bad Gateway, the next thing you should do is check your WordPress site’s .htaccess file.
The .htaccess file is a server configuration file that helps control how WordPress works.
To check your .htaccess file, you’ll need to connect to your WordPress site via FTP. Once you’re connected, navigate to the /wp-content/ folder.
Inside the /wp-content/ folder, you should see a file named .htaccess. If you don’t see this file, make sure that you have set your FTP client to show hidden files.
Once you’ve found the .htaccess file, download it to your computer.
Next, open the .htaccess file in a text editor and look for any code that looks suspicious. If you see any code that you don’t recognize, delete it and then save your changes.
After you’ve edited the .htaccess file, upload it back to your WordPress site and try accessing the URL again. If you’re still seeing a 502 Error Bad Gateway, move on to the next method.
Method 7: Contact Your Hosting Provider
If you’ve tried all of the methods above and you’re still seeing a 502 Bad Gateway, then the issue is most likely with your web hosting provider.
In this case, you’ll need to contact your hosting provider and let them know about the 502 Bad Gateway error. They should be able to help you fix the issue.
