What is 502 Bad Gateway?

It is a generic error. In simple words, it means your web server acts as a proxy for different servers. It is due to a bedridden response that arises from an upstream server.

This error is a generally known HTTP status code. It can occur on any device or browser. This means there are issues with your site’s server communication.
