Laravel websocket cant connect to pusher ERR_CERT_AUTHORITY_INVALID

I have a laravel application with websockets. I already setup all the needs for the websocket and pusher config. But whenever I test my broadcast channel I got

app.js:58283 WebSocket connection to 'wss://127.0.0.1/app/644a4ac1988060882370?protocol=7&client=js&version=6.0.2&flash=false' failed: Error in connection establishment: net::ERR_CERT_AUTHORITY_INVALID

When i do some reload. sometimes i get app.js:55791 WebSocket connection to 'wss://127.0.0.1/app/644a4ac1988060882370?protocol=7&client=js&version=6.0.2&flash=false' failed: WebSocket is closed before the connection is established.

Here are my configs.

broadcasting.php

   'pusher' => [
            'driver' => 'pusher',
            'key' => env('PUSHER_APP_KEY'),

            'app_id' => env('PUSHER_APP_ID'),
            'options' => [
                'cluster' => env('PUSHER_APP_CLUSTER'),
                'encrypted' => true,
                'host' => '127.0.0.1',

                'scheme' => 'http',
            ],
        ],

websockets.php

            'enable_statistics' => true,
            'verify_peer' => false,
        ],
    ],

bootstrap.js

import Echo from "laravel-echo"
window.Pusher = require('pusher-js');

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: 'xxxxxxxxxxxxxxx',
    wsHost: window.location.hostname,
    wsPort: 6001,
    disableStats: true,
    // enabledTransports: ['ws', 'wss']
});

window.Echo.channel('Inventory').listen('InventoryEvent',(e)=>{
    console.log(e)
})

web.php

Route::get('/', function () {
    broadcast(new InventoryEvent('somedata'));
    return view('welcome');
});

InventoryEvent

I already setup the env for my pusher credentials. Do i need to config something in my pusher in order for this to work? I got another project with the same setup but it works but this one is not.

Try downgrading your pusher-js package to version 4.3.1. Thats what I am using and it works well. Latest version always seems to listen on secure wss instead of the non-secure ws.
