What do you mean by "hit the appliance or SSH to the servers"? Please be more precise for us to be able to help.
After installation have you have configured IP address and other network related configurations. Mentioned here.
If yes, then could you ping, telnet (on tcp port 22) to appliance from where you are trying to access the appliance?
We don't have much information from your description. But, you can try using the IP address of the appliance instead of the hostname.
I would try bringing up a putty session as the "tideway" user and use the ssh putty method to bring up the command-line for the new appliance.
If the connection is good, but the password fails, then you have a different problem.
We need more data from you. You can't ping? Or, you can't login with the password???
Can you ping your gateway from the appliance?
