Thanks for every one!
This issue seems to disappear after the change in config. Our site is more stable than ever before in the last week with a rather short response time during the whole week.
WebSocket connection to 'ws://factions.im/socket.io/1/websocket/IAyxkSG8SXnS9p6VX8Xr' failed: Error during WebSocket handshake: 'Connection' header value is not 'Upgrade' socket.io.js:2
GET http://factions.im/socket.io/1/xhr-polling/IAyxkSG8SXnS9p6VX8Xr?t=1390721548115 504 (Gateway Time-out)
For some reason the server never detects my login and then leaves me hanging there. But still shows my admin panel icon and that's how I login. But I feel that for other users it may be different. What can I do to fix the speed for the Socket.IO request? The only reason why it is failing so far is because of the load time.
I also would like to note the stats don't show up for my NodeBB install as well.
Looks like your web sockets are not working. Are you proxying requests using nginx? You need version 1.3.13 or later.
