Egg on face. The 2 days issue ended up a problem in my epoch conversion routine. I am using RTCZero instead. The WiFi.getTime() works just fine.
The second part of my original post was a misdiagnosis of the symptoms at hand. The problem was NOT related to fetching NTP or anything else for that matter.
I use a MOFI router with CloudLink VPN and public IP through which I connect with the MKR-1010 from anywhere. While this works OK it will cause WiFiNINA to hang exactly every hour. There is some activity related to the CloudLink VPN that causes the rounter to not respond to ping for a short while but then also causing WiFiNINA to hang. After disabling the VPN for testing purposes, the MKR has not shown any connection or hanging issues for over 1 day. We know that the VPN causes the issue, but I have no idea about the exact reason why.

The behavior is identical with using WiFi.getTime(). Although executed within the firmware, it appears that getTime() synchronizes once every hour and the MKR1010 fails (hangs) exactly once every hour after start/restart.
