I have been hosting adguard home on a local raspberry pi for a few years now. A few moths ago I changed everything around as I wanted to host more on that pi and moved to a docker setup.
Everything works, but I see that I have about 70k dns queries in 24 hours. and about 90 percent of that is just a query for "." from an IP which I guess is my raspberry pi's interal docker IP?
Ok, so I managed to figure it out, as soon as I took down wireguard the constant query stopped.
So now I move wireguard to one of other pi's and everything is working as it should.
Thanks for all the help!
