no Network, interface have no MAC

[galaxyhiker]

Hello everyone,
since this weekend, I can no longer access the Proxmox WebGUI, neither on the host nor on the VMs.
The interface eno1 is down, when attempting "ip link set dev eno1 up," I receive the error message "RENETLINK answer: Cannot assign requested address.".
I also try to change the ether in /etc/network/interface per "hwaddress ether 11:22:33:44:55:66" in eno1 and vmbr0
Local from the PVE machin i can ping to the VMs.

Have someone maybe a Idee what can i do,

General Information:

UPDATE 23.04:
withe a USB Adapter Netwerk works. My guess is a defect in the network card.

After some firmware updates, the graphics card is now correctly recognized, but unfortunately, still no interface is being displayed.

I'm currently using the USB adapter and can connect to Proxmox. However, the VMs have no network connection. It was working with the USB adapter yesterday. I'm slightly annoyed (at the server and myself). I haven't changed anything since then

Did you happen to do some system updates and upgraded your kernel recently?

Updates were applied midweek, and everything ran smoothly afterward.
I restarted the VMs, and they were able to connect again. The network card seemed to be defective; I also informed the seller and, after reviewing some logs, they agreed that the network card was indeed faulty and sent us a replacement.
