[SOLVED] Unable to access internet on new host

Greetings,

I just installed proxmox on a second host today (pveh2), added it to a cluster, and tried to access the web on it but it's not working. I'm not sure if the fact that I added it to a cluster immediately after install proxmox is relevant.

Code:
$ curl ifcfg.me
curl: (6) Could not resolve host: ifcfg.me

$ apt update
...W: Failed to fetch http://ftp.us.debian.org/debian/dists/bookworm/InRelease  Temporary failure resolving 'ftp.us.debian.org'...

I have already compared /etc/network/interface and /etc/hosts, and the output of ip a on both machines. The second machine (pveh2) has all very similar configurations, except of course the hostname and the host IP.

Any ideas as to what I should try next?

Code:
root@pveh2:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vmbr0 state UP group default qlen 1000
    link/ether 6c:2b:59:e2:81:34 brd ff:ff:ff:ff:ff:ff
    altname enp0s31f6
3: vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 6c:2b:59:e2:81:34 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.4/24 scope global vmbr0
       valid_lft forever preferred_lft forever
    inet6 fe80::6e2b:59ff:fee2:8134/64 scope link
       valid_lft forever preferred_lft forever

Code:
127.0.0.1 localhost.localdomain localhost
192.168.1.4 pveh2.teachers.local pveh2

# The following lines are desirable for IPv6 capable hosts

::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Code:
root@pveh2:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.1.4/24
        gateway 192.168.1.1
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

By the way -- I know the host clock is out of sync on the second machine. I was hoping to connect it to the internet to fix that.
 
That was it, somehow nameserver was set to 127.0.0.1... maybe because I installed proxmox with no connection?

Thanks for your insanely fast reply
