How to Fix a 502 Bad Gateway Error on Your WordPress Site?

The 502 Bad Gateway error indicates that an incoming server sent an invalid response to the server.

The 502 Bad Gateway error is defined by the Internet Engineering Task Force (IETF) as follows:

The 502 (Bad Gateway) status code indicates that the server, while acting as a gateway or proxy, received an invalid response from an inbound server it accessed while attempting to fulfill the request.

Your browser makes a request to a web server every time you visit a website. The web server receives the request, processes it, and then delivers the requested resources, along with an HTTP header and an HTTP status code. An HTTP status code isn’t typically seen unless something goes wrong. It’s basically the server’s way of informing you that something has gone wrong and giving you the code to diagnose the problem.

500 status error codes come in a variety of formats (500, 501, 502, 503, 504, 508, 520, etc), within each set of meanings. These indicate that the request was accepted, but the server prevented the fulfillment of the request.

Variations of the 502 Bad Gateway Error

A 502 bad gateway error can appear in a variety of ways depending on the browser, web server, and operating system used. They all mean the same thing, though. Here are a few of the many different variants you could come across on the web:

And here’s another take on the theme. “502 – While acting as a gateway or proxy server, the webserver got an invalid response. The page you’re looking for can’t be displayed because there’s a problem with it. When the Web server contacted the upstream content server (while acting as a gateway or proxy), the content server returned an invalid response.”

502 Errors Impact on SEO

A 502 error, unlike 503 errors, which are used for WordPress maintenance mode and tell Google to come again later, can have a negative impact on SEO if not fixed straight away. If your site is only down for 10 minutes and is crawled frequently, the crawler will just fetch the page from the cache. Or Google might not have a chance to better it before it goes down again. You’re perfectly fine in this situation.

If the site is down for a long time, say 6 hours or more, Google may view the 502 error as a site-level issue that has to be addressed. This may have an impact on your rankings. If you’re worried about repeating 502 errors, you should first figure out why they’re happening. Some of the ideas below may be helpful.
