Hello guys, i have a problem with network interface in Proxmox. My company has a VPS on contabo, in this server was installed Debian 11, but for our business we will need a virtualized server that supports some PABX VMs. It turns out that we installed Proxmox via command line following the tutorial: https://docs.vultr.com/how-to-install-proxmox-virtual-environment-on-debian-11
The installation was successful. But when I create a VM, no network interface option appears . What do I need to do to fix this? The public IP that contabo provides me is the same IP as the internal network of my proxmox (seen by the ifconfig command)

Nothing appears here
