Socket.io - SSL through Cloudflare

I've read through nearly every possible tutorial about how to receive SSL through socket.io and I just can't seem to get it to work.

My backend JS is as follows:

var express = require('express');

var options = {
    key: fs.readFileSync('/key.key'),
    cert: fs.readFileSync('/crt.crt'),
    requestCert: true
};
var app = express();
var server = require('https').createServer(options, app);
var io = require('socket.io').listen(server);
server.listen(2096, "IP Address");

The frontend JS:

SOCKET = io('https://name.com:443', {secure: true});

I'm using full SSL, with cloudflare signed certificates install on my server.

I also receive the following error when connecting:

POST https://name.com/socket.io/?EIO=3&transport=polling&t=LcBk2Vk 404()

I'm not sure if my ports are incorrect or I'm missing something entirely.

I'm happy to provide more code snippets.

Thanks in advance

You are simply listening on the wrong port. SSL traffic is served over 443 usually, in order to fix this you should substitute:

server.listen(2096, "IP Address");

With something like this:

server.listen(443);
