When I try to debug this is the error that I have. I tried changing the resolve.conf, but tailscale writes over it. Maybe this isn’t even a pihole issue; it could be a tailscale issue.
[✗] DNS resolution is currently unavailable
[i] Waiting up to 120 seconds for DNS resolution
I do have to say that I changed some settings in tailscale. Then I Restarted DNS resolver and flushed the network logs. As of now it seems to be working again. Hopefully it lasts. I ran your commands though. Here are the results:
admin@RaspPiHole:~ $ cat /etc/resolv.conf
# resolv.conf(5) file generated by tailscale
# For more info, see https://tailscale.com/s/resolvconf-overwrite
# DO NOT EDIT THIS FILE BY HAND -- CHANGES WILL BE OVERWRITTEN

I appreciate your help. I saw what you were saying when I ran tailscale dns status where it told me to run sudo tailscale set --accept-dns=false . So I ran it also. It didn’t say whether it went through or not, so I assume that it did. I put what my upsteam dns is set at. Is that correct? Again thank you!
$ tailscale dns status

(Run 'tailscale set --accept-dns=true' to start sending DNS queries to the Tailscale DNS resolver)

Id recommend having in /etc/resolv.conf not exclusively servers from the local machine(this would also include unbound) and at least one trusted public resolver. This will make troubleshooting easier when something goes wrong with the local DNS server. You can just add 1.1.1.1 or a different trusted public resolver as a fallback option, on a newline in /etc/resolv.conf.
