DNS Weirdness (uCore & Bluefin)

General
1

Greetings programs.
I am running a UniFI network at my home (please refrain from comments on this) and have defined a local DNS on my UDM Pro. I have updated my DHCP server to reflect the local domain (echenique.local) and have added the following three A records:

echenique.local    A    192.168.1.1
vaultboy.echenique.local    A   192.168.1.168
exodar.echenique.local    A    192.168.1.95

I have rebooted my Bluefin machine to enable the DHCP update and have confirmed that the DNS registrations are correct. However, pinging vaultboy.echenique.local returns:

ping: vaultboy.echenique.local: Temporary failure in name resolution

and nslookup vaultboy 192.168.1.1 returns

Server:		192.168.1.1
Address:	192.168.1.1#53

Name:	vaultboy
Address: 192.168.1.168

also changing the hostname of 192.168.1.168 to vaultboy using hostnamectl kind of breaks login to Cockpit. Not sure what is happening there.

Any and all assistance is greatly appreciated.

Turns out I had to open the DNS/DNS-Over-TLS ports in firewalld to allow the traffic to get punted around the local network. This was on both the Bluefin machine and the uCore server. Have to make a note of that.

Could you provide the specific instructs you used?

IIRC I modified it through Cockpit.
Edit: CONFIRMED. I added the respective ports there.
