ERROR 504 – GATEWAY TIMEOUT
Why am I seeing this page?
The server that your request has reached is acting as a gateway or proxy to fulfil the request made by your client.
Web Browser => Web Front-End => Web Back-End
This server (Web Front-End) received an invalid response from an upstream (Web Back-End) server it accessed to fulfil the request.
In most cases this will not mean that the upstream server is down, but rather that the upstream server and the gateway/proxy do not agree on the protocol for exchanging data.
This problem is most commonly caused when there is a problem with IP communications between the Web Front and Back-Ends. Before you attempt to resolve this problem you should clear your browser cache completely.
