I am not trying to block any Youtube ads. I just signed up for Youtub tv and encountered some weird behavior. Checking my logs I was not blocking anything but things would still not load. I ended up removing all my block lists as well as disabling pi hole. As long as I have pi hole set as my DNS, videos fail to load regardless of the fact nothing is blocked. As soon as i set the DNS to 1.1.1.1 everything works fine.
I'm not sure how this link helps, or am I missing something? Like I mentioned in my post I am not trying to block any ads for Youtube TV, I simply want the service to work.
I checked all my query logs and in fact deleted all my block lists and whitelists and the problem still occurs. The fact that the DNS requests are routed through pi hole seems to be causing issues. The debug token link added was taken with no block lists with nothing blocked.
The debug log provided shows that Pi-hole is not resolving anything:
*** [ DIAGNOSING ]: Name resolution (IPv4) using a random blocked domain and a known ad-serving domain
[✗] Failed to resolve via localhost (127.0.0.1)
[✗] Failed to resolve via Pi-hole (192.168.1.249)
[✓] doubleclick.com is 142.250.72.206 via a remote, public DNS server (8.8.8.8)
It also shows that no queries are going to Pi-hole:

I would expect that the clients have no ability to resolve any names if they are ointed to 192.168.1.249 as their DNS server. Are you running any firewalls? Have you run pihole -r and attempted a repair?
ahhh hmm i might have cleared the logs before i generated it. lemme recreate it after trying a repair.

Ah, I figured out what was going on when collecting logs again. Previously i was grep-ing for blocked and black listed requests. Was just doinga tail this time and reading. Noticed a bunch of url's were being resolved by my /etc/hosts file. I guess some script added add those in and I never noticed. Removed those and things are working as expected.
edit: realized the hosts file entry's seem to be left over from an older version of pi hole since most things were migrated to the block list properly.
I guess feature request is to log host file resolutions in a diff color too to make debugging a bit easier
thanks for all the help guys
tldr; checks hosts file in addition to gravity/blocklist configurations
thanks for all the help guys
