The 504 Gateway Timeout error is an HTTP status code that means that one server did not receive a timely response from another server that it was accessing while attempting to load the web page or fill another request by the browser. This usually means that the other server is down or not working properly.

The 504 Gateway Timeout error is usually a network error between servers on the Internet or an issue with an actual server, meaning the problem is not with your PC or Internet connection. Even though the issue is not yours to troubleshoot or resolve, there are a few things you can do: Retry the web page by clicking the refresh/reload button or trying the URL from the address bar again. Even though the 504 Gateway Timeout error is reporting an error outside of your control, the error may only be temporary. Trying the page again will often be successful.

A server (not necessarily a Web server) is acting as a gateway or proxy to fulfil the request by the client (e.g. your Web browser) to access the requested URL. This server did not receive a timely response from an upstream server it accessed to deal with your HTTP request.

This usually means that the upstream server is down (no response to the gateway/proxy), rather than that the upstream server and the gateway/proxy do not agree on the protocol for exchanging data.

This problem is entirely due to slow IP communication between back-end computers, possibly including your Web server. Only the people who set up the network at the site which hosts the Web server can fix this problem.

Sounds like network connections from client side. During error time, can you visit other websites such as google.com ? Are you connecting via proxy ? what about the proxy connection to your host? As you interpreted, it is not likely your server end having problem.
