10060 is a Winsock error code, meaning that the connection timed out. 
That suggests that the host name is completely incorrect, because you're 
not even contacting a real host that can reject the connection.

If you're familiar with the TCP protocol, this means the SYN packet is 
going out, and no SYN/ACK (or RST) is coming back.

This assumes that there are no firewalls in the way.  If that's the 
case, then the host name could be correct, but the firewall is dropping 
the SYN packet silently.  Firewalls often do this for "stealthing" reasons.
