GPU removal

[duus]

After installing proxmox VE I could not remove the graphics card from the server, I assume it is as that changes the numbering of the network card. I accepted that for a while, but now I want to transfer the server to a actual rack chassis and that would require removing the GPU (not to mention the unnessecary power usage)

I tried following this step here:
Post in thread '[SOLVED] Remove GPU after installation' https://forum.proxmox.com/threads/solved-remove-gpu-after-installation.122780/post-535250

But after doing that (using name=enp2s0 instead of eth0), the network card absolutely refuses to connect to my network again. I tried removing the file, to no avail.

Here is my current setup:
/etc/network/interfaces

auto lo
iface lo inet manual

iface enp2s0

auto vmbr0
iface vmbr0 inet static
        address 192.168.5.10/24
        gateway 192.168.5.1
        bridge-ports enp2s0
        bridge-stp off
        bridge-fd 0

source /etc/network/interfaces.d*

any help would be greatly appreciated. I can only access the machine with a screen directly hooked up right now

Turned out problem was my unifi dream machine absolutely refusing to let it use the static ip i set. I have my server services on the 192.168.5.0 network while the rest of my online devices are on 192.168.1.0. Had to use dhcp in the interface setup, then tell unifi that I wanted it to be on 192.168.5.2.

Apart from that the link i added worked fine, just had to use enp2s0 as name.
