[LayaNative 1.0]native 1.0.2 连不上wss

<html>

<head>

<body>

    <script>

    var ws = new WebSocket("wss://login.huanxi.twbuyu.com:27777");

    ws.onopen = function() {

        alert("connect success~");

        ws.send('tom');

        alert("send to server msg: tom");

    };

    ws.onmessage = function(e) {

        alert("accpet msg: " + e.data);

    };

    ws.onerror = function(e) {

        alert("error: " + e);

        console.log(e)

    };

    </script>

</body>

</html>

这是app设置的url所对应的html文件，在web端是能连上socket的，app里面就连不上
（简单起见这里直接使用原生websocket，使用laya封装的socket效果一样）

xcode部分日志如下：

看起来像是证书问题，可是web端是能访问的，不清楚什么问题
