i ddn’t have wireguard-tools installed, but I will certainly try that now that you’ve suggested it.
Also I have a bit of an update on the issue, after the latest nordvpn update (3.12.1) it started happening sometimes every 2 hours and 10 minutes, which is quite interesting, since it went from 4 hours 20 minutes to 2 hours and 10 minutes, it’s like the duration between connection breaks got cut exactly by half.
