I noticed that opnsense after a reboot gave an error in the log of UDP-proxy-2020 (and the first reboot after updating to OPNsense 22.7.2-amd64 from zenarmor saying the same, any reboot there after zenarmor makes no mention of this anymore) that there is no WG0 interface.
But when rebooting is completed, there surely is a WG0 interface and wireguard is running.
msg="Unable to find interface: wg0: route ip+net: no such network interface"
Somebody else also have this "error" in the log / error in zenarmor first time after upgrading?
