Minimwatch stopped working immediately as scanning was completed

[echable]

PC is connected via 5ghz wifi, NAS by cable.

I uninstalled all Java, and reinstalled 64-bit offline installer.

I then uninstalled and reinstalled Minimwatch. The icon is now not red, but grey.

In options - properties - oh.subnet I have entered 255.255.255.0.

According to the network settings on the NAS, that is the subnet my NAS is on. I also double-checked with ipconfig /all.

Does Minimwatch work with either of the 32 bit or 64 bit Java install ?

I have tried completely turning of absolutely everything of firewall software, anti-virus, VPN etc. Minimwatch still doesn't turn green. Funny thing is, when I first installed it, it was also green for a few hours, before suddenly turning grey again.

My computer is connected to a VPN. I suppose this may complicate things ?
