**The easiest solution would be simply to choose a different network interface and bind it to your external IP (for instance, your Wi-Fi IP).**
If for some reason you really want to bind to `127.0.0.1`, read the explanation below.
Ubuntu comes with a local DNS server by default - "systemd-resolved" which uses 53 port and thus prevents AdGuard Home from binding to it. To fix this, you should disable "systemd-resolved" daemon. Luckily, AdGuard Home can detect such configurations and disable "systemd-resolved" for you if you press "Fix" button which is shown near to "address already in use" message.
