[SOLVED] Connection lost right after GUI is visible

[paradoxcydal]

Hey all,

not really a forum poster but here goes as I don't know what is going on.
So I have proxmox VE 7 installed and everything was working fine with my on-board NIC. I wanted to install a second NIC (for tinkering with PfSense), System boots, still gets the static IP from the on-board NIC but there is no way of reaching the GUI anymore.

The first 5 seconds when the system is up i have a network connection but after those 5 seconds i lose connectivity (I think the second NIC gets initialized? which drops the link).

I have no idea where to start looking.. please help!

edit: https://forum.proxmox.com/threads/pve-6-4-to-7-no-network-only-for-host.98198/#post-425362

looks like my exact problem but I can't seem to figure out which hardware address i should try and match.

Hi,

Can you post the return of(for your HOST):

- ifconfig
- route -n (if not installed, return of "ip r"
- lsof -i

I just found the solution! The ip -c link wouldnt return the NIC, i changed the pcie slot and then all of a sudden everything worked, Seemed to be a hardware based issue!
