I believe that with the latest release, there is an additional Roon component that needs to be added to the Firewall exceptions for certain configurations of Roon.
The roonappliance.exe should be in the list for these configurations.
Yes, everything is up and running after I reinstalled Roon. After looking at a few other threads I believe that after the update there was a service or component that need Windows firewall permission. That was probably fixed by reinstalling Roon.
