Error in SIOCSIFADDR_IN6 on FreeBSD 14.2 amd64

[zod076]

So I just setup yggdrasil.conf on a FreeBSD 14.2 VPS and when I start the service manually, I notice the following:

# yggdrasil -useconffile yggdrasil.conf

The first is the 'Error' and second is the 'ifconfig' command which uses /dev/tun0 instead of just tun0. Doing ifconfig tun0 results in 'interface tun0 does not exists' error but ifconfig /dev/tun0 works.

Is this something to be concerned about ?
