HogNet with different versions of OS

Hi 
HogPC 3.17.1 cannot see the show that a Road Hog 3.17.0 is running! 
They are both connected on a DHCP router with cable (no WIFI on laptop)
Obtain IP using DHCP for both
Run Server - Run Processor ON for both
Net Number 1 for both
Ping from Laptop with the console IP is OK
Restart to everything but still "No Show Found " both ways
Any suggestions? Is it possible that the versions difference causes the problem?
Thanks
