Windows Server 2012 UrBackup client unable to connect to UrBackup Server

UrBackup Server 2.3.7 is running on a Windows 7 Ultimate machine.
UrBackup Client 2.3.4 is running SUCCESSFULLY on a Windows 7 Ultimate machine
UrBackup Client 2.3.4 is installed on a Windows Server 2012 machine and is not able to discover the UrBackup server. All machines are on the same network running the same subnet mask.

Windows Firewall is configured to allow both UrBackupClient EXEs to access the network.
I have also disabled the firewall completely. Doesn’t seem to change the results.

On the UrBackup server, I have added the client as a suggestion… It shows as online YES, but nothing else happens.

When using netstat, I see no connections from client to server. Only connections seen are the client backend is connected to the tray app.

On the Windows 7 client, I see the connections from the backend to the tray app along with connection(s) to the server.

I’m not sure what else to try.

Any suggestions?
