Origin going as HTTP in laravel websockets

I am using Laravel websockets but Origin is going http instead of https.

Here are my files

Broadcasting.php

'connections' => [
    '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' => false,
            'host' => 'domainlink',
            'port' => 6001,
            'scheme' => 'https',
            'useTLS' => true,
            'curl_options' => [
                CURLOPT_SSL_VERIFYHOST => 0,
                CURLOPT_SSL_VERIFYPEER => 0,
            ]
     ],
 ],

websockets.php

'ssl' => [
    /*
     * Path to local certificate file on filesystem. It must be a PEM encoded file which
     * contains your certificate and private key. It can optionally contain the
     * certificate chain of issuers. The private key also may be contained
     * in a separate file specified by local_pk.
     */
    'local_cert' => 'fullchain.pem',

    /*
     * Path to local private key file on filesystem in case of separate files for
     * certificate (local_cert) and private key.
     */
    'local_pk' =>'privkey.pem',

    /*
     * Passphrase for your local_cert file.
     */
    'passphrase' => env('LARAVEL_WEBSOCKETS_SSL_PASSPHRASE', null),

    'verify_peer' => false,

    'allow_self_signed' => true,
    
],

app.js

  window.Echo = new Echo({
     broadcaster: 'pusher',
     key: "L698gJH67",
     encrypted: false,
     wsHost: window.location.hostname,
     wssHost: window.location.hostname,
     wsPort: 6001,
     wssPort: 6001,
     forceTLS: true,
     disableStats: true,
     enabledTransports: ['ws', 'wss'],
  });

Connection with socket is successful but while broadcasting message I am getting Invalid auth signature provided and if I change schema to http in broadcast.php I get Pusher error: cURL error 52: Empty reply from server.

Not sure what I am doing wrong. Thanks for the help in advance.
