New KVM install DNS issue

Installing HA as a VM on my Unraid machine. Booting from the extracted qcow2 disk works fine, but the web page shows ‘preparing’ forever. Checking the supervisor logs it looks to be a DNS issue. I can resolve the site fine, and if I make a manually entry for ghcr.io in the hosts file to the address I get from nslookup I can get through the initial setup, but then it fails to update with a similar issue for github.com.

Repeating logs:

nslookup output:

# nslookup ghcr.io
Server: 192.168.1.1
Address: 192.168.1.1:53

Name: ghcr.io
Address: 140.82.112.33
