Some simple diagnostics to get further with this problem.

First is to isolate the source of the problem, whether it is SSH, or
simply the network / DNS.

Try using telnet to connect to the port instead, for example, if I
connect to my local machine on port 22, I get the following, which
clearly shows that OpenSSH is running.

]$ telnet localhost 22
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
SSH-2.0-OpenSSH_5.2
^]
telnet> close
Connection closed.

However if I try and connect to a port with nothing running I get:

]$ telnet localhost 1234
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused

As well as doing this, you can check the IP address that is returned, it
may be that you are not resolving the right IP address for the machine.

Those are good starting points
