I have a very frustrating bug in Safari on MacOs Tahoe. When I set Adgurd Home as my DNS server, I get very rare DNS fail. It fails only in Safari, other commands such as dig, Chrome works. It fails in curl as well. After around 30sec-1minute it resolves fine.
I think the problem is in getaddrinfo(), curl and Safari uses that.
I am running Adgurd Home in Proxmox LXC container.
