MinimServer not working post upgrade

This sounds like it might be a firewall issue on the PC preventing inbound UPnP connections to MinimServer. You need to have firewall exceptions for inbound connections to the Java runtime for both TCP and UDP on all ports. To confirm that this is the problem, you can completely disable the firewall on the PC as a test.

You should also check that the network on your PC is configured as private, not public. The Windows firewall blocks UPnP by default on public networks.
