Hi,
is your firmware update to date? Maybe there is a new BIOS .

It completely hangs or the network stops working? The NUC8i has a problem with the standard driver under load (but it self-recovers).

If it hangs, i would recommend to run memtest too.

My /etc/network/interfaces looks like:

auto lo
iface lo inet loopback

iface eno1 inet manual
  post-up /usr/sbin/ethtool -K eno1 gso off gro off tso off tx off rx off rxvlan off txvlan off sg off

auto vmbr0
iface vmbr0 inet static
        address 192.168.XXX.YYY/24
        gateway 192.168.XXX.YYY
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

i just checked it is up to date

Not sure as i run it headless machine.... i can probably keep it with monitor akd keyboard connected to check next time it happens

Thank you
Does your nuc hangs/freeze at all ?
i run home firewall via it may be it doesn't like it once it is frozen.... is there any way for me to check some logs ?

I have a fixed IP, you do not seem to use it?

But my 2 Intel NUC8i, neither hang ... but network was unstable , until i added the ethtool line.

i have now added that line and plugged in a USB ethernet adapter to see if that freeze too if not i will be able to figure out something if onboard network crashes

Mine never crashed ... but if this does not work, check also with a monitor/keyboard ... If you see a kernel panic, it is something else.
