Socket.IO not getting disconnect event on polling

Question

My browser is defaulting to "polling" method, causing me not to get the disconnect event on the server side.

I've tried the solution covered in socket.io force a disconnect over XHR-polling but this didn't do the trick for me:

Server.socket = io.connect("https://somedomain:8443", {"sync disconnect on unload":true, secure:true});

How can I track users leaving my server with polling?

as a fallback to websocket which is not supported in all mobile browsers. — trueicecold, Nov 11 '16 at 20:05

so, apparently for some reason the heartbeat timeout was too long for me to think the disconnect mechanism was working.

I changed the timings:

var io = require('socket.io')(server, {'pingInterval': 4000, 'pingTimeout': 8000});

In the server, and after 8 seconds, sure thing, I get the disconnect event. The low numbers are because I'm creating a multiplayer game...
