能不能有前輩可以幫我看看！
今天為了測試html5 web 開啟相機掃描 QR 功能，因為需要 https 連線，所以索性將本地開發機 ，掛上 固定 ip 並使用 sslfree 的免費證書，安裝好之後卻發生如下報錯 ：

WebSocket connection to 'wss://我的域名?protocol=7&client=js&version=7.0.2&flash=false' failed: Error during WebSocket handshake: Unexpected response code: 404

這應該怎麼處裡??

我的pusher 設定如下：
1、config/websockets.php

... 省略
    '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,
        ],
    ],

...省略

2、config/broadcasting.php

... 省略
        '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',
                'port' => 6001,
                'scheme' => 'http'  //這裡曾嘗試修改成https => 結果無效
            ],
        ],

...省略

3、bootstrap.js

... 省略
import Echo from 'laravel-echo';

window.Pusher = require('pusher-js');

window.Echo = new Echo({
    broadcaster: 'pusher',
    key: '我的密碼',
    wsHost: window.location.hostname,
    wsPort: 6001,
    forceTLS: false,
    disableStats: true,
});

...省略

期待前輩指導，謝謝！
