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?

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

auto enp6s0
iface enp6s0 static

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

This worked, however I have now installed a new PCIe SSD which apparantly changed it again and I have the same thing again. The adapter name was already changed. The LAN port also doesn't blink anymore just once on bootup.

You can follow

• https://pve.proxmox.com/wiki/Network_Configuration#_naming_conventions # Overriding network device names
• https://wiki.debian.org/NetworkInterfaceNames#CUSTOM_SCHEMES_USING_.LINK_FILES

to establish a static name of your choice.

1. auto enps70 -> auto enp7s0 (That line should not be necessary...)
2. bridge-ports enp6s0 -> bridge-ports enp7s0
3. Reboot the host

I set it to enp7s0 already. Is it maybe the hosts file? The node is called pve, how do I find out the other entries I need to make on that IP?

It appears in my fritzbox router now but its still not reachable. Webinterface says "connection refused".
