Hi @harshitsx2020,
Bad Gateway errors are often caused by issues between online servers that you have no control over.
Try following the steps below. Any of them would work out for you depending on the problem.

  1. Start a new browser session by closing all open browser windows and then opening a new one. Then try opening the web page again.
    It’s possible that the 502 error you received was due to an issue on your computer that occurred sometime during this use of your browser.
    A simple restart of the browser program itself could solve the problem.

  2. Clear your browser’s cache

(https://www.lifewire.com/how-to-clear-cache-2617980). Outdated or corrupted files that are being stored by your browser could be causing 502 Bad Gateway issue.

Removing those cached files and trying the page again will solve the problem if this is the cause.

  1. Restart your computer

Some temporary issues with your computer and how it’s connecting to your network could be causing 502 errors, especially if you’re seeing the error on more than one website. In these cases, a restart would help.

  1. DNS Issue

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.

You can also try flushing your local DNS cache. This is similar to clearing your browser cache.

In Windows simply open up Command Prompt and enter the following:
You can check out here:

  1. Clear your browser’s cookies and also try removing suspicious plugins and extensions in your web browser.

  2. Try using a different web browser and see if the problem persists.

  3. Check If the Site Is Down For Other People

Whenever you fail to reach a site (for whatever reason), you can also check if it’s just you that’s having a problem connecting, or if other people are having the same trouble. There are lots of tools out there for this like isitdownrightnow.com and downforeveryoneorjustme.com. Both work pretty much the same. Plug in the URL you want to check, and you’ll get a result like this.


If you get a report saying the site is down for everyone, there’s not much you can do but try again later. If the report shows that the site is up, then the problem might be on your end. It’s very rare if this is the case with a 502 error, but it is possible.

Hi ,
