Currently, I faced a 502 bad gateway response error. Though it got solved by just refreshing the page, I was wondering why did it occur? Can anyone simplify this for me?
A 502 bad gateway response error occurs when the proxy server is unable to get a response from the main server. To simplify things, when you search something on your browser, say Google, it does not get directly to the main server.
Rather there is an intermediary server known as the proxy server which redirects your request to the main server (here, Google server). So, due to some reason, the proxy server could not get a response from the Google server or the main server, and you got the error message. On refreshing, the proxy server was able to receive the response, and your problem was solved.
