Minimserver not seen by Minimwatch and devices

[Donuk]

I speak with no deep knowledge but I would put an outside bet on it being a problem of addresses and the components in your home network are not talking to each other properly.
I would try rebooting the router - it may reallocate addresses better - and reboot the PC - or wait for an expert to come along.
I have found VPNs can obstruct things. If you use one, try switching it off your PC for testing purposes.

Hope this helps
