[solved] Strange Error after deleting GIF HE.net IPv6 tunnel latest RC

strangegopher

Hi,

I often see following log entries that I didn't see before removing HE.net tunnel in latest RC build.
78.46.223.24 is nordvpn dns server i entered in system -> general setup
The errors were similar to 78.46.223.24 but with quad9 ipv6 dns servers earlier but then I removed ipv6 dns servers from system -> general setup and then I started seeing following errors.

I created a ticket: https://redmine.pfsense.org/issues/8390

I partially fixed the issue by adding dns 2620:fe::fe and then deleting it.

Now I only see one error message at bootup (and no error at openvpn up/changing unbound settings/changing dns):

Just did fresh install and restored config, still see errors.

my config.xml file had <dns5gw>NORDVPN_DHCP</dns5gw>
despite having no DNS entries in System/Advanced

changed it to <dns5gw>none</dns5gw> and problem solved!

I would like to thank the source code for helping me narrow down the problem.
