Laravel 5.4 with Pusher Illuminate\Broadcasting\BroadcastException' with message '404 NOT FOUND

I'm attempting to get Pusher working with Laravel 5.4, but I keep running into the push failing in the queue. I've tested the Channel from the Pusher debug console and it works without issue. I can also see the browser listening on the chosen channel. I've followed the setup on the Pusher getting started page. I've used artisan to clear config and cache, done a httpd restart as well to be sure.

I don't know if I am missing a step, or something else. I've seen this question asked a few times on here, but each solution which I've encorporated below, doesn't resolve the issue.

Hoping someone can come up with a suggestion.

Thanks in advance.

Setup

.env (Setup, and checked is working correctly):

APP_URL=*****
DB_HOST=*****
BROADCAST_DRIVER=pusher
PUSHER_APP_ID=******
PUSHER_APP_KEY=*******************
PUSHER_APP_SECRET=***********************

broadcasting.php (Added CURL options, no success):

    'pusher' => [
        'driver' => 'pusher',
        'key' => config('services.pusher.app_key'),
        'secret' => config('services.pusher.app_secret'),
        'app_id' => config('services.pusher.app_id'),
        'options' => [
            'cluster' => 'ap4',
            'useTLS' => true,
            'curl_options' => [
                CURLOPT_SSL_VERIFYHOST => 0,
                CURLOPT_SSL_VERIFYPEER => 0,
            ]
        ],
    ],

TicketComment.php (Event)

<?php

namespace App\Events;

use Illuminate\Queue\SerializesModels;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;

class TicketComment implements ShouldBroadcast
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    public $tries = 5;

    public $username;

    public $message;

    /**
     * Create a new event instance.
     *
     * @return void
     */
    public function __construct($username)
    {
        $this->username = $username;
        $this->message  = "{$username} liked your status";
    }

    /**
     * Get the channels the event should broadcast on.
     *
     * @return Channel|array
     */
    public function broadcastOn()
    {
        return ['status-liked'];
    }

    public function broadcastAs() {

        return 'event-liked';

    }
}

global.js (front-end js):

    var _notificationListener = function(){
        // Enable pusher logging - don't include this in production
        Pusher.logToConsole = true;

        var pusher = new Pusher('*******************', {
            cluster: 'ap4',
            encrypted: true
        });

        var channel = pusher.subscribe('my-channel');
        channel.bind('event-liked', function(data) {
            alert(JSON.stringify(data));
        });
}
