1: What is a 502 Bad Gateway Error?
The 502 Bad Gateway Error requires you to understand how hosting WordPress involves multiple servers. Usually, you have the application server, the database server, the reverse proxy server, the webserver that stores the static files and a CDN which is the optional performance server (Know more about 5 Best WordPress CDN Plugins). When you enter the site, your browser will send requests to the proxy server. And that will initiate a set of requests to the other servers. In case one of the servers is sending an invalid response to the proxy server, then that means the site will not be loading inside the browser. And that will lead to the 502 Bad Gateway Error.
The causes behind a 502 Bad Gateway Error can differ here. For example, you may have faulty PHP code, DNS issues, misbehaving the browser cache, CDN network problems, the server might not be configured properly, the offline server brings in issues or the upstream server is overloaded. These are all things to keep in mind as the 502 Bad Gateway Error can easily differ in causes. And thus it can become very hard to find a fix for it, as you have to know what caused it in the first place.

2.1 – Clear Your Browser Cache & Refresh/Reload Your Site
A good thing to focus on is to perform a hard refresh on the browser, you can do that with CTRL + F5 pressed at the same time in the browser. It might actually solve the problem a lot faster than you imagine, all you have to do is to make the right pick and choose to work on it with the proper attention that will work quite nicely if you do it right.
It can be related to a hosting issue, in that case refreshing is the best way to go.

Just take your time and try to figure out what causes the issue, to begin with, it might help eliminate a lot of hassle while still helping you a lot here.
2.2 – Disable Your CDN Temporarily
As we mentioned earlier, sometimes the 502 Bad Gateway Error might be caused by a CDN like KeyCDN or Cloudflare. These help rout the traffic via their servers so you have better security and performance. But obviously not all their servers are the best, so you will encounter some issues along the way at times. Which is why you want to pause the CDN and refresh the site to see if the 502 Bad Gateway Error will persist or not. In case it will all work well once you stop the CDN, then you just have to talk with their support and see how you can handle this correctly.How to fix 502 bad Gateway Error in #WordPress ❓❓❓ Check out really useful & handpicked ✔️✔️ #WordPressTips from #WpSmallFix These all tips are easy to implement and will fix the error. #WordPressSupport #WordPressHelp Click To Tweet
2.3 – Troubleshooting Plugins & Theme
Sometimes the 502 Bad Gateway Error might be from your plugins or theme. That might not always be the case, but it can be a possibility, so you have to prepare for a situation like that if possible. Login to the root directory via your File Manager or Filezilla, navigate the wp_content and then find plugins. Rename that folder and then refresh the site to see if the error persists. If it still persists, rename it back to the old name.
Then you can move to theme troubleshooting. In this case you want to go to the themes side of the same folder, rename and if the theme is causing issues, you will notice that the 502 Bad Gateway Error disappears. If not, then you will go back to rename to the older name and move on to other troubleshooting. Also, know more about How to Update WordPress Theme Without Losing Customization
