Socket.io with VVV - Messages not being received on client

Question

I'm running VVV (Vagrant) with socket-io-redis. This seems to be working, the messages are sending to Redis.

I test with SUBSCRIBE socket.io#/# which is logging a bunch of messages for testing.

This is an example of the response I'm seeing in terminal -

1) "message" 2) "socket.io#/#" 3) "\x93\xa7emitter\x83\xa4type\x02\xa4data\x92\xa4time\xb82016-04-03T22:17:21.478Z\xa3nsp\xa1/\x82\xa5rooms\x90\xa5flags\x80"

Node JS -

var redis = require('socket.io-redis');
var io = require('socket.io')(3000);

io.adapter(redis({ host: '192.168.50.4', port: 6379 }));

// Handle opened socket connections
io.on('connection', function(socket) {
    console.log( 'Connection' );
});

var io = require('socket.io-emitter')({ host: '192.168.50.4', port: 6379 });
setInterval(function(){
  io.emit('time', new Date);
}, 5000);

Client -

( function( window, undefined ) {
    'use strict';

    var socket = io( '192.168.50.4:3000', {transports:['websocket']} );

    socket.on( 'time', function() {
        console.log( 'Received time' );
    });

    socket.on( 'connect', function() {
        console.log( 'Connected' );
        console.log( socket );
    });

} )( this );

When I run the Node app I see the message Connection, in the console of my browser I see the message Connected (then the socket for debug).

I cant' see anything obviously wrong, the client connects and the emitter seems to be working. But nothing emitted is ever received by the client.

Am I missing something? The IPs are not local host due to running Vagrant.

Any advice appreciated. Thanks!

EDIT:

Quick update, I can emit without using socket.io-emitter, however it doesn't go through Redis. When I use emitter, it goes through Redis correctly, as mentioned above.

It seems as though my client isn't receiving the messages from Redis, even though the ports are open.

Here's what I try -

socket.emit( 'new_post', 'Nope' );

var io = require('socket.io-emitter')({ host: '192.168.50.4', port: 6379 });
io.emit( 'new_post', 'Yep' );

In my browser I see Nope but nothing else. I then monitor Redis and see the following -

"publish" "socket.io#/#" "\x93\xa7emitter\x83\xa4type\x02\xa4data\x92\xa8new_post\xa3Yep\xa3nsp\xa1/\x82\xa5rooms\x90\xa5flags\x90"

My server also doesn't see messages when using Redis, I test with -

socket.on( 'new_post', function( msg ){
    socket.emit( 'new_post', msg );
});
