UrBackup server is in different subnet and clients(Desktop) in different subnet in the same location.
is there any way to make server to communicate with different subnet any help on this greatly help for me.
Use internet mode.
I’d imagine so, can the client ping it & get replies? It probably took you longer to ask than try 
@Bearded_Blunder Thanks for your Reply.
I have enabled with Private IP and configured it is working fine.
