Hi,
today i couldn’t get into my proxmox server.
I just added a new nvme to my system, but now there is no eth connection anymore. Before proxmox boot, the ethernet port leds flash, but then they go out.
I have the deskmini x300 with
Athlon 200ge
2x sata ssd
New: 1xnvme, above the wifi slot.

all drives are recognized in the bios.

I ran systemctl status networking and one output was

Code:
...
networking[947]: error: vmbr0: bridge port enp1s0 does not exist
...

this can happen - you add a new pci-e device, which means that for certain mainboards the pci-addresses of the other devices shift around.
This in turn renames the NIC in systemd's "predictable" network interface naming scheme - https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/

from the screenshot and the logs you posted I guess that `enp1s0` got renamed to `enp2s0`

-> edit /etc/network/interfaces and replace enp1s0 with enp2s0 and reboot

I hope this helps!

I just registered to say thanks! This one worked for me, after installing an PCIe M.2.
