We now have version 5.3.25 and cannot get even the admins to connect now. The server is running 2012r2 so does not have that update, but we do have some updates from the 14th so im uninstalling one at a time to see if this sorts the connection issue.
We have noticed DLL errors within the logs and the error below all the time:
CCSS4: ImperoClientSVC53252016-05-25 16:20:17System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 10.20.20.74:30016
