Hey Luke,

I had the same problem when trying zeromq for the first time. For me, it
turned out that things were being blocked on the server side. Check out
your iptables and make sure you are allowing ingoing and outgoing traffic
on the port you are binding to. You may want to check the firewall settings
on your client as well.
