我知道我可能不会在这里得到任何答案，但这是我的镜头。
基本上我使用此代码HERE
我可以使用 ws：// （不安全的连接）在我的服务器上完成所有工作，但当我切换到 wss：// （安全连接）时无法连接，我收到以下错误：
failed: Error during WebSocket handshake: Unexpected response code: 500
这是我的wss：//代码：
var wsUri = "wss://example.com:443/websocket/server.php";
这是我不安全的ws：//连接（工作）
var wsUri = "ws://example.com:9000/websocket/server.php";
说实话，我不知道自己做错了什么。有人可以就这个问题提出建议吗？
我通过SSH启动websocket服务器（server.php），这是我开始时看到的：

我认为如果我对第一个错误进行了排序，大部分错误都会消失，但我并不真正理解这意味着什么，也不知道我需要做些什么！
现在错误更改为：
failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
