It's working fine, when i tried with val socket = Socket(serverAddress, PORT) .

Here is the code snippet that i am using

AsyncServer.getDefault().listen(host, port, new ListenCallback() {

           @Override
           public void onAccepted(final AsyncSocket socket) {
               handleAccept(socket);
           }

           @Override
           public void onListening(AsyncServerSocket socket) {
               System.out.println("[Server] Server started listening for connections");
           }

           @Override
           public void onCompleted(Exception ex) {
               if(ex != null) throw new RuntimeException(ex);
               System.out.println("[Server] Successfully shutdown server");
           }
       });

Is there anything i am missing?
