Block youtube ADs with PiHole blacklist

I have experienced that sites can detect the adblocker running in the browser.
And some sites are not happy.

But the most important reason i use pi-hole, is that it is "site (vlan) wide".
No need for adblocker or ....
And i can add my own blocks easily.

For me it broke YouTube. Videos that start with an add never play. Had to remove the list.

Sometimes it's not possible. You just can't force user to use it.

@w0w Do you use that list on anything that is not a browser client?

Had such a list in PiHole and used it on Chromecasts, Android TVs etc. and no device with a YouTube App worked anymore as the preroll Ads won't show and the actual video doesn't get triggered then. Even looking at 2min black screen it doesn't skip to the video. Was the same as @AndyRH and had to remove the list for the TVs and FireTVs as neither did work (yes of course a few videos get played when there's no ads/monetization on them, but most do today).

@jegr
it still showing Ads and videos on the Youtube App on all android devices I have tried. But if I use any android browser client instead of app, no more Ads displayed on the Youtube.
Don't know maybe Google uses same servers for streaming Ads and videos in different countries or maybe some other settings in pfBlockerNG have been changed. My Whitelist contains

I think it is default. I've added only s.youtube.com entry, but it does not matter. It works the same way with or without it.

My android phone refuses to use the DNS server provided by the DHCP when using Youtube app..
Through firewall logs, I can see it using 8.8.8.8.. So it's bypassing DNSBL completely..

It seems that my chromecast is doing the same thing:

@mcury
I've captured some packets and for me it looks like now Youtube App uses some version of DNS over HTTPS. I don't see public DNS server IPs in captured data

@w0w
If that is the case, there DoH blocklists in pfBlockerNG. Or maybe I got them from GitHub, been a while.
https://raw.githubusercontent.com/oneoffdallas/dohservers/master/list.txt
https://raw.githubusercontent.com/Sekhan/TheGreatWall/master/TheGreatWall.txt
That, and setting a rule for all LAN DNS requests to loop back to the FW might work.

Added both and now Youtube App never plays videos with Ads

Same for me. The DoH lists seem to be working fine, though.
