Proxmox doesn't have internet access

[Son_Of_Diablo]

Hello,

I'm trying to setup proxmox, but my installation doesn't have access to the internet or the local network.

I have tried googling around, but haven't been able to find a solution, so now I'm here.

I have taken a few screenshots (sorry for the quality, I can't really take actual screenshots or copy as the installation is on a separate machine).

ip a

ip route

cat /etc/network/interfaces

cat /etc/hosts

ping 1.1.1.1

trying to reach the internet

ping 10.0.0.1

trying to reach the local network (pinging the gateway)




I know it's not the hardware, the server Proxmox is installed on has some underlying system that exposes a web interface and I'm able to reach that.
But Proxmox doesn't have a connection, so I'm assuming the issue is with the Proxmox installation.


Any suggestions on how to resolve this issue would be greatly appriciated!
I probably won't be able to test any of the suggestions until next Monday, but would still appreciate all the suggestions you can give me!


Many thanks in advance!

Your network interfaces are down. Check/post journalctl for anything related.

As @daanw said, you network interfaces are all down, double check the Physical server cables connections and also on the switch side.
