504 Gateway Timeout
This server error indicates a gateway, or proxy, server did not receive a response within the time allowed.
This error occurs when either the gateway server or an upstream server are busy, or unresponsive.
The error does not specify which server is the problem or the cause of the problem.
In some cases, this problem could be caused by high activity causing one of the servers to be overwhelmed. In such a case, re-attempting later may resolve if the server is no longer busy.
There is no more client-side troubleshooting available. If the issue is unexpected or persists then contact the appropriate server support.
The HyperText Transfer Protocol (HTTP) 504 Gateway Timeout server error response code indicates that the server, while acting as a gateway or proxy, did not get a response in time from the upstream server that it needed in order to complete the request.
Note: A Gateway might refer to different things in networking and a 504 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.
