IOS connection disconnects immediately

I'm connecting to my kryonet server, from IOS using a simple socket connection API.

It disconnects as the code cannot find udpRemoteAddres

What is udpRemoteAddress, and how can I pass it from the client. From a java client, I can pass the udp port as a second param, but from IOS I see the API allows only one socket address to be passed.

Please help in understanding if I can connect to kryonet using normal socket API's or will I need a kryonet client.
