Tried all of the ports and security settings I could find and it simply would not connect. It turned out that while attempting to connect I was always connected to the Wifi at work and I believe that is why it wouldn't connect to the server (not sure why). When the wifi disconnected and I tried again it worked (Wow! Alot of wasted time)
