Connect to FTP server via TLS

Good Day, I'm having trouble uploading an image to a FTP server via TLS on Android 4.4 with Titanium SDK 3.4.0.GA. I'm able to connect to the server, but that's as far as i've gotten. After it connects, when I try to log into the server, I get the following message: [INFO] : Received: 550 TLS handshake failed What is going wrong? Here is my code: [App.js]

var mediaFileToUpload = '';
 
var win = Titanium.UI.createWindow({backgroundColor:'white'});
 
var connectButton = Titanium.UI.createButton({
title:'Connect',
top: 155,
left:30,
right:30,
height:40
});
win.add(connectButton);
var upB = Titanium.UI.createButton({
title:'upload',
top: 195,
left:30,
right:30,
height:40
});
win.add(upB);
upB.addEventListener('click', function(e){
    logout();
});
var controlSocket = Ti.Network.Socket.createTCP({
host:'xxx.xxx.xxx.xxx',
