I installed virtualmin on a fresh Ubuntu 20.04 install.
I created 2 virtual servers. The first one let’s say was named example1 and the second example 1.
hostname for server is example1.com
Virtualmin set up Bind with:
zone 0 Master example2 Master
Root Zone root localhost Master
127 master example1 master
At the registrar Nameserver for example 2 is NS1.example1.com
I suspect Bind setup is incorrect but I have no idea how to correct it.
