Sending request to localhost

[quique0194]

I'm working in Calthorpe in the Urbanfootprint project. We are using amigocloud-js and at some points it sends a request to Urbanfootprint server. The request looks like this:

http://172.28.128.3/socket.io/1/?t=1443712707258

Where 172.28.128.3 is the vagrant machine IP. In other words Urbanfootprint's IP.
And this is the response:

{"code":0,"message":"Transport unknown"}

The request is sent in this line: https://github.com/amigocloud/amigocloud-js/blob/master/amigocloud.js#L11193

Socket.prototype.handshake = function (fn) {
    ...
    function complete (data) {
        ...
        xhr.send(null);      // Here is the bug
    }
};
