The 502 Bad Gateway error is an HTTP status code that means that one server received an invalid response from another server.

There can be many factors why does this error shows.

But in most cases it is because of .htaccess file.
Login into your FTP, in root rentame .htaccess file to .htaccess-old or anything else so it will be inactive but you can backup it just by renaming it and deleting that "-old" extension.

This is a dedicated server with plenty of resources available and it only started after HHVM was installed. The admin panel became very slow until Redis was installed but that didn't help the issue of timing out. I didn't initially time out but now I can't post or update without timing out but the data does get saved to the DB.

The 502 error is produced by WP Engine that signals a request for either a page, script, process, or query has taken too long to complete and has been cancelled (killed). The digits, 5xx and 02, are HTTP Status Codes which correspond to 5xx meaning Server Error while 02 refers to Bad Gateway.

Hi,

– 502 Bad Gateway is likely a server error, not a WordPress issue. Try contacting your hosting provider.
– Meanwhile, try clearing your cookies, cache. Also, try a different browser.

Thanks.
