Hi all,

I am facing a weird issue with one of my proxmox boxes, the machine connects to the internet and I am able to install the os. Once rebooted it can no longer, ping the gateway therefore no longer having network access.

However if I do boot windows from the same machine (I have windows on a separate drive) it does work fine.

Network configuration is basic and hasn't changed, 1 router to the internet, proxmox wired into there, 1 nic.

It's really frustrating, I have another proxmox machine connected to the same router and doesn't show this problem.

I am running 6.2-1 on both with the same level of updates.

What could it be?

Thanks

Pascal
 
I think this is related to the main NIC enp2s0 DOWN and vmbr0 being UNKNOWN?

Apologies for the picture quality, but I can only screenshot, since no network.

This has been fixed by replacing enp3s0 inside /etc/network/interfaces to enp2s0 which is the only one I have - any idea what can have caused this? I didn't make any change to interfaces at all!
