Use laravel wecsockets and Echo with SSL

Hello,

I'm having trouble configuring Laravel websockets and Echo with SSL. (Everything works fine without encryption).

Here are my settings:

Bootstrap.js

window.Echo = new Echo({
    'broadcaster' : 'pusher',
    'key': '123456789',
    'wsHost' : window.location.hostname,
    'wsPort' : 6001,
    'wssPort' : 6001,
    'forceTLS' : true,
    'disableStats' : true,
    'cluster' : 'eu',
    'encrypted' : true
}) ;

config/broadcasting.php

'pusher' => [
            'driver' => 'pusher',
            'key' => env('PUSHER_APP_KEY'),
            'secret' => env('PUSHER_APP_SECRET'),
            'app_id' => env('PUSHER_APP_ID'),
            'options' => [
                'cluster' => env('PUSHER_APP_CLUSTER'),
                'encrypted' => true,
                'host' => "127.0.0.1",
                'useTLS' => true,
                'port' => 6001,
                'scheme' => 'https',
                'curl_options' => [
                    CURLOPT_SSL_VERIFYHOST => 0,
                    CURLOPT_SSL_VERIFYPEER => 0,
                ]
            ],
        ],

config/websockets.php

'apps' => [
        [
            'id' => env('PUSHER_APP_ID'),
            'name' => env('APP_NAME'),
            'key' => env('PUSHER_APP_KEY'),
            'secret' => env('PUSHER_APP_SECRET'),
            'path' => env('PUSHER_APP_PATH'),
            'capacity' => null,
            'enable_client_messages' => false,
            'enable_statistics' => true,
            'encrypted' => true,
        ],
    ],

I have 2 problems:

• On firefox, the connection with the WSS is not done... "the connection was interrupted while the page was loading."
• On Chrome, it only works if I disable "peer_verify". Which doesn't help me, since my goal is to have an end-to-end encryption...

Do you have any ideas that would help me?

Thanks!
