1. Try to connect with a command line tool (curl, wget,...). If that doesn't work, then all stuff on client side can be ignore for now.
2. Connection Refused means that the class-server will not even see an attempted connection. It is refused at OS level. I would guess that there is a firewall blocking port 4160, OR that the class-server has not bound the listener to the interface you are trying to connect on. You should be able to use (on Linux) "iptables --list" to verify firewall rules (might be overwhelmingly complex) and "netstat -tulpn" to check what/how is bound to 4160 port.
