404 errors indicates that the resource you are currently looking for is unavailable
502 error indicates that the proxy server doesn't receive proper response from the main server.

A 404 error is an HTTP status code that means that the page you were trying to reach on a website couldn't be found on their server. The 404 Not Found error might appear for several reasons even though no real issue exists, so sometimes a simple refresh will often load the page you were looking for. The most common method is to retry the web page by pressing F5, clicking the refresh/reload button, or trying the URL from the address bar again.

The 502 Bad Gateway error is an HTTP status code that means that one server on the internet received an invalid response from another server. 502 Bad Gateway errors are completely independent of your particular setup, meaning that you could see one in any browser, on any operating system, and on any device.
