The HyperText Transfer Protocol (HTTP) 502 Bad Gateway server error response code indicates that the server, while acting as a gateway or proxy, received an invalid response from the upstream server.
Note: A Gateway might refer to different things in networking and a 502 error is usually not something you can fix, but requires a fix by the web server or the proxies you are trying to get access through.
