Earlier quoted context omitted.
Same. When my cell has an ip6 ip, I can’t get dns to resolve on my systems at home. I can still access everything by ip4 ip though. I haven’t had time to find a solution yet. I’m still trying to figure out if it’s nginx, pi-hole, router, or Tailscale config related… probably a combination.
I encountered a similar issue when I first started using Tailscale. My fix is simple: disable IPv4 inside Tailscale. Just use the v6 ULA address that begins with fd7a exclusively. This works even if your ISP doesn't support IPv6: the inner IPv6 packets can be encapsulated inside v4 packets. There's unfortunately no GUI to do this; you'll have to change the Tailscale ACL to disable IPv4.
TIL this is a thing

perfect, this is exactly what I desired
(I'm having an increasingly high number of sad v4 only LAN devices and planned to move to a v4 block that sits way too close to the one Tailscale uses.)

ah that's why I missed it, thanks!
