Webinterface not reachable after mainboard change

[DivineLight]

Hello,

I downgraded from a B550M-TUF to a B350M-A. Proxmox is installed on a 250 GB 960 EVO, it boots without issues but the webinterface is not reachable. My router also does not discover any connected device. The port however seems to function, it blinks when I plug in the cable.

These are my current settings:



The adapter name in the /etc/networking/interfaces was already changed. I tried several supposed fixes on similar issues on Google but nothing helped. Reinstalling is not really an option because of my VM configuration, redoing all of this would be insane effort. How do I reset the proxmox Linux network adapter to factory settings?

NO-CARRIER typically indicates a problem with the cable or physical ports. Make sure it is connected and/or another cable and/or another port on the router side.

/etc/network/interfaces is wrong: You declared enp6s0 multiple times.

auto enp6s0
iface enp6s0 static

Replace both occurences of enp6s0 by „vmbr0“. Then reboot.
