Can't access webgui after a reboot

[katamari92]

#installed fine
#first reboot was fine setup some stuff just learning mostly
#second reboot and the web gui refuses to load
#go poking about and find out network is frelled
#technically dhcp no other computers change ip (will turn it static as soon as the router can see it. it's not on the lease list(strange))
#will update with more. hit me.

#edit: added hosts and hostname pic. What else can I get for you guys?

IGNORE ALL THAT GARBAGE! pics too.

I added a graphics card to the system which changed the load order of the devices. very annoying.
I still want to use the graphics card in one of the vms, how do I add the graphics card without breaking everything!
I have the BIOS/UEFI set to prioritize the iGPU over the dGPU.

I want to not be stuck to a broken system everytime I toss in an add-on card. how do I fix this when it breaks?

I'm glad that I have a problem so unique that no one knows how to reconfigure a network interface to make it work again.

You can specify NIC names by MAC, see https://pve.proxmox.com/wiki/Network_Configuration#_naming_conventions. PVE 9 has a command line utility to pin names.

It's not the reboot but it's because of adding a PCI(e) device. The name on the network devices is determined by their PCI ID (by default) and the PCI IDs change when PCI(e) devices are added, removed, enabled or disabled. Check the new name with ip a (it's probably enp4s0 now) and change /etc/network/interfaces accordingly. Lots of threads about this on other parts of the forum. Or change the network device naming using the post above this one.
