minimwatch unable to detect minimserver

[QTEC]

Simon,

Problem :- minimwatch showing grey icon indicating minimserver on NAS is not running.
Equipment :- Laptop running windows 10, latest version of Java, and latest version of minimwatch.
Qnap Nas running latest version of minimserver.
NAIM NDX controlled by Naim app.
The minimserver is working perfectly well via the naim app.
A few days ago the internet was changed to fibre and a new router fitted.
I suspected this was causing the problem with minimwatch so I loaded minimwatch onto my old desktop running windows vista and connected to the new router and this worked ok.
The problem appears to be with windows 10 and minimwatch on the laptop.
I tried deleting and reloading both java and minimwatch and running jarfix as suggested in a previous thread.
I have tried disabling the firewall on the laptop and router.
Hope you can help.
