Problem connecting to the soketi on the server

Question

I am going to setup a websocket I have used soketi package

But I am facing a problem in connecting to the web socket which now i will get this error

code: 4001 message: "App key ---- does not exist." event: "pusher:error"

In general, I have done this to set up the web socket: soketi server :

sub domain : socket.example.com

installing apt install -y git python3 gcc build-essential npm install -g @soketi/soketi

soketi config json

{
    "debug": true,
    "port": 443,
    "appManager.array.apps": [
        {
            "id": "---",
            "key": "---",
            "secret": "----"
        }
    ]
}

broadcast :

'host' => env('PUSHER_HOST', '127.0.0.1'),
'port' => env('PUSHER_PORT', 6001),
'scheme' => env('PUSHER_SCHEME', 'http'),
'encrypted' => true,
useTLS' => env('PUSHER_SCHEME') === 'https'

env config:

BROADCAST_DRIVER=pusher
PUSHER_APP_ID=---
PUSHER_APP_KEY=---
PUSHER_APP_SECRET=---
PUSHER_APP_CLUSTER=ap2
PUSHER_SCHEME=https
PUSHER_PORT=443
PUSHER_HOST=127.0.0.1
SOKETI_SSL_CERT=/etc/nginx/ssl/socket.example.com/----/server.crt
SOKETI_SSL_KEY=/etc/nginx/ssl/socket.wourki.com/----/server.key

run soketi soketi start --config=soketi.json

Connect to WebSockets in the main project: domain : example.com

broadcast

'host' => env('PUSHER_HOST', '127.0.0.1'),
'port' => env('PUSHER_PORT', 6001),
'scheme' => env('PUSHER_SCHEME', 'http'),
'encrypted' => true,
useTLS' => env('PUSHER_SCHEME') === 'https'

env config

BROADCAST_DRIVER=pusher
PUSHER_APP_ID=---
PUSHER_APP_KEY=---
PUSHER_APP_SECRET=---
PUSHER_APP_CLUSTER=ap2
PUSHER_SCHEME=https
PUSHER_PORT=443
PUSHER_HOST='socket.example.com'

laravel echo

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: '----',
    cluster: 'ap2',
    forceTLS: true,
    wsHost:'socket.example.com',
    wsPort:6001,
    wssPort:443,
    encrypted: true,
    disableStats: true,
    enabledTransports: ['ws', 'wss']
});

So far, I have not had the experience of setting up a web socket. I would be grateful if you could guide me Or introduce me to a tutorial for this
