Customize AdGuard Home DNS Servers and Settings

But now I have come to a point where I don't know in which direction to investigate further. I don't have much experience in terms of networks or DNS but I know the basics. So the DNS is just set up as a forwarding DNS which forwards all host names it cannot resolve itself to Google's servers 8.8.8.8 and 8.8.4.4. I basically just set it up in order to resolve the host names inside my local network comfortably. I posted my issue here on serverfault since I strongly believe it must've something to do with the bind9 DNS server I installed a few months ago on my Banana Pi. At the same time, access through YouTube's web site works flawlessly (from both phones), same applies to accessing it from my PC or laptop and for the rest of the internet. Strange thing is, it ONLY happens with the YouTube app on my Android phone and my wife's iPhone.

The app frequently shows a "check your network connection" message when I open it up while the rest of the internet is working just fine. For quite some time now I'm encountering an annoying issue regarding the YouTube app while on my home network.
