MinimServer unreachable since updates

[Animal]

Java (8.101) is indeed orange and MinimServer is green in the App Center.
Have tried yet again and stopped both and then started Java first and then MinimServer, both running but can't open MinimServer from the App Center.
I seem to remember some other updates for several of the *** Station apps from QNAP at the same time (though I don't use any of them) ...
No idea why this suddenly happens and nothing else changed in my network etc.?
