Error during WebSocket handshake: Status line does not end with CRLF

[cindoum]

Everytime socket try to connect i got an error :
WebSocket connection to 'wss://playground-c9-doum.c9.io/socket.io/1/websocket/QBGO1ZlPhWUBkMVQ9cUP' failed: Error during WebSocket handshake: Status line does not end with CRLF socket.io.js:2371

On server side :

var io = socket.listen(server);
var store = require('connect-mongo')(express);

io.set('authorization', passportSocketIo.authorize({
    passport: require('passport'),
    cookieParser: express.cookieParser,
    key:         'connect.sid',       // the name of the cookie where express/connect     stores its session_id
    secret:      constant.SALT,    // the session_secret to parse the cookie
    store:       new store({
        mongoose_connection: db,
        collection: constant.SESSION_COLLECTION,
    }),
    success:     onAuthorizeSuccess,  // *optional* callback on success - read more below
    fail:        onAuthorizeFail,
}));

io.sockets.on('connection', function (socket) {
    socket.on('chat:newText', function (data) {
        console.log(socket.handshake.user);
        data.username = socket.handshake.user.username;
        io.sockets.emit('chat:newText', data);
    });
});

client side :

var connect = function () {
    if (Auth.isLoggedIn() === true) {
        socket = io.connect();
        connected = true;
        return true;
    }
    else {
        console.log('Socket wont connect as user is not logged in');
        return false;
    }
};
