HA Pi-hole config static DNS servers

I have since found this thread which I think has solved my problem:

This is what I did:

  • disable and stop unbound-resolvconf.service
  • commenting resolv_conf=/etc/resolv.conf and unbound_conf=/var/cache/unbound/resolvconf_resolvers.conf in /etc/resolvconf.conf
  • deleting /etc/unbound/unbound.conf.d/resolvconf_resolvers.conf
  • reboot
