With the VPN disconnected:
root@DietPi:~# ip -4 ro
default via 192.168.50.1 dev eth0 onlink
192.168.50.0/24 dev eth0 proto kernel scope link src 192.168.50.254
With the VPN connected:
root@DietPi:~# ip -4 ro
0.0.0.0/1 via 10.8.0.1 dev tun0
default via 192.168.50.1 dev eth0 onlink
10.8.0.0/24 dev tun0 proto kernel scope link src 10.8.0.2

So, it seems NordVPN’s tunnel is up. Right?
