I also had a problem with passing statistics like in twan69666 (Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because of the target machine actively refused it 127.0.0.1:3333 at System .Net.Sockets.Socket.DoConnect (EndPoint endPointSnapshot, SocketAddress socketAddress)). The firewall is disabled. OS - Windows 7. On another computer on the network, this problem does not arise.
