Problem connecting to Android

Hello Nelderson. Only the desktop version works and on localhost. If you try to use it on your mobile phone with wi-fi it is not working and it will be locked on the screen of the image that I sent. I await your help.

In the image below you have an error example using the Droid4X android emulator. The error only happens if you try to use with android.

OK. I was able to tidy up and connect now. Thanks a lot for the help.

var allowCrossDomain = function(req, res, next) {
    res.header('Access-Control-Allow-Origin', '*');
    res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
    res.header('Access-Control-Allow-Headers', 'Content-Type, x-access-token');
    if (req.method === "OPTIONS") 
        res.send(200);
    else 
        next();
}
