Websocket opcode 7 with wss

So, i try to launch a server in wss:// since Tuesday but it doesn't work, today i decide to look WebSocket code and i found why my WebSocket closed directly. This is error code i find:

1002 Unsupported usage of rsv bits without negotiated extension.
VALUE OF RSV1:Opcode: 7, fin: false, length: 69, hasPayload: true, masked: false

My program works with ws:// but not with wss://. I can't understand why tls blocked.

I precise IPtables are stopped and my certificate is OK.

Do you have any idea?

Below is my code if you want to look:

var fs = require('fs');
var https = require('https');
var WebSocketServer = require('websocket').server;
var express = require('express');

var serverTLS = express.createServer({
    key: fs.readFileSync(__dirname + '/notification_mail/notification.mail.com.key'),
    cert: fs.readFileSync(__dirname + '/notification_mail/notification.mail.com.crt')
});


serverTLS.configure(function(){
    serverTLS.set('views',__dirname);
    serverTLS.set('view engine','ejs');
});

serverTLS.get('/',function(req,res){
    res.render('index',{layout: false });
});

serverTLS.listen("443");

var wss = new WebSocketServer({ httpServer: serverTLS, autoAcceptConnections: true });

wss.on('connect', function(connection) {
    console.log((new Date()) + " Connection accepted.");

    connection.on('close', function(connection) {
            console.log((new Date()) + " Disconnected");
    });
});

console.log("Server launch");

And my html file

<html>
<head>
 <meta charset="utf-8">
 <title>Example</title>
</head>
<body>
<h1>Serveur 2</h1>
<div id="tchat"></div>
<script>
   var url = "wss://notification.mail.com";
   var wsCtor = window['MozWebSocket'] ? MozWebSocket : WebSocket;
   this.socket = new wsCtor(url, 'connect');

   this.socket.onclose = function(){
      alert ("Connection lost");
   }
</script>
</body>
</html>

The error message is confusing, since

Did you try Chrome or IE10?

You could also try running AutobahnTestsuite against your node server.

The testsuite has a fuzzingclient mode that supports WSS. The testsuite includes extensive wire log reports which might help finding out what happens.
