i haven't had internet on the host from the start. only noticed when trying to download a CT template and started troubleshooting from there.

when trying nslookup using an external server i also get a timeout:
root@oracle:~# nslookup google.com 8.8.8.8
;; connection timed out; no servers could be reached
root@oracle:~# nslookup google.com
Server: 192.168.178.1
Address: 192.168.178.1#53
Non-authoritative answer:
Name: google.com
Address: 142.250.179.142
Name: google.com
Address: 2a00:1450:400e:801::200e
tried different values in resolv.conf, even external DNS without success. nslookups on local DNS resolve immediatly.
