OK....  Had you left it hanging then had I run "nmap -sS 108.220.213.1" should have shown the
port "open"

See the comments below.

This series on 4/13 is "good".  Listening on all interfaces

Probably a "systemctl restart named" issued.  PID 905 is shutting down.

And a new PID 309193 is starting.  Also 309193 shows "good"

The next day when name is started again we no longer see....

listening on IPv4 interface eno1, 10.0.0.101#53

So, what happened?  What changed?  All subsequent entries are "bad".

For "fun" how about rebooting the system?
