Can someone explain to me what bad Gateway error means and why does this happen? Is it a client-side error or a server-side error and would it cause any problem in the network?
Understanding HTTP Error Code 502 And Its Solution
Bad Gateway error or the HTTP status code 502, means that the server is either a gateway or a proxy server and that it is not receiving a valid response from the backend service which is actually supposed to give the requested information to the main server. The most common method adopted for fixing this issue is to clear your browser’s cache the reason this can happen is because of corrupted or outdated files that are still present in the browser.
You can also close all the previously opened tabs and start a new browser session, or by refreshing the page and by deleting all the cookies. If there is any immediate work to be done, then you can start your browser in safe mode. Running a browser in safe mode means that no additional plugins, themes or extensions that were previously downloaded will be included.
Understanding HTTP Error Code 502 And Its Solution
The “502 Bad Gateway” error you see on websites is an HTTP status code which means a server on the internet received an invalid response from another server. This is a server-side error which I encountered once on my website. The cause can be a problem with the configuration of your website or from the server itself.
If you have a website and you encounter this, check the files on your site for wrong setting. If nothing seems to be wrong with your site’s configuration, you can assume that the problem is with the server itself and expect that the problem will be fixed after a few hours. Frequently, errors like this are caused by problems between servers online that you have no control over.
What you can do when you encounter this is to try reloading the page. Press F5 on your keyboard to refresh the page or press CTRL + F5 to force refresh the page. If this doesn’t work, restart your web browser and open the page or URL again. If this doesn’t work either, empty your browser’s cache.
You can also try deleting the cookies on your browser to possibly remove a corrupt cookie but doing this will log you out of all your accounts that are currently logged in. Another way is to open the URL or page on a different web browser.
