Thank you for this great Project! Really helpful.

I currently experience some issues with setting up the Domain, i am running the latest Version inside Docker, checked if Port 53 is opened in the Firewall and the API itself works but whenever i Ping a created Subdomain i am getting the following Error:

cannot resolve http://home.dyndns-ns.domain.tld: Unknown host

My Domain Setup is as follows:

dyndns-ns (NS) -> dyndns.domain.tld
dyndns (A) -> IP-Address of the Server

In the ZONE .env Variable i have dyndns.domain.tld

The Ports are exposed and everything except the Nameserver itself seems to work, am i missing anything? I am running the Docker Container on Ubuntu 20.04, systemd-resolve is disabled.
