Seeking some help here. I have my homelab on a Pi running some services and want to access them with a custom domain name, which was working fine until a mysterious error cropped up a month or two ago on Android.
To resolve the DNS, I have AdGuard Home on my router with a custom routing for the domain pointed at my local ip address, and for good measure I also put the local ip in a public DNS record.
This actually works fine on my Mac, and worked fine on Android until recently. Now, I get a DNS error `DNS_PROBE_POSSIBLE`. I tried a couple different Android phones with the same result.
I do have a VPN on my phone, it's supposed to be set to allow local IPs, and the error still occurs when I turn the VPN off. So the only way I can see the VPN being related is if it's poisoning the DNS cache.
