RatChet PHP-websocket的问题

我用Ratchet做了一个webchat，它在我的计算机上运行得很好，如果我用命令行启动脚本，它就会运行，如果我在另一个浏览器中打开聊天的本地主机，它就会运行得很好，我可以和我的另一个浏览器聊天，然后，我做了，我感到很奇怪，但我尝试部署我的聊天，并与我的朋友分享，看看它是否真的对每个人都有效，而不是对每个人都有效，只发送消息，没有人能看到，因此，我不知道websocket是否真的有效，或者问题是否出在服务器主机上，因为我使用000webhost，使用websocket可能不太好

来源：chat server.php

<?php
    use Ratchet\Server\IoServer;
    use Ratchet\Http\HttpServer;
    use Ratchet\WebSocket\WsServer;
    use Ricardo\Socket\Chat;

    require 'vendor/autoload.php';

        $server = IoServer::factory(
            new HttpServer(
                new WsServer(
                    new Chat()
                )
            ),
            8080
        );

        $server->run();

嗯，我只发送了这些来源，因为在我看来这很重要，请帮忙
