[SOLVED] Not connecting to network anymore

[Miura]

I've been running Proxmox succesfully for a while now, surviving reboots and whatnot. However, currently it doesn't connect to my network anymore, although it does show the message that it's available at the giving url-port.

Searching through the forums I came along some suggestions about a 'corrupted' interfaces file. I've been digging to come with the problem but can't figure it out. Below a photo of

• cat /etc/network/interfaces
• cat /etc/hosts
• ip a

Tested to be OK:

• UTP Cable
• Port on Router (Ubiquity UDM Base)

Hi,

given the output, enp2s0 is reported as having the flag NO-CARRIER. In other words, this means the physical interface is not properly connected to the other side (the Ubiquity router in your case, I guess)

Is the cable properly connected on both sides? Do the link LEDs light up?

Thanks a lot for your answer. I do not see any light on either end of the cable. I have been trying several cables and several ports on my router, so I am quite confident that it's not that part of the hardware. I am running on a Intel NUC NUC12WSHi50Z which only has 1 LAN port.

I might have a USB-A to LAN dongle lying around somewhere, so I'll give that a try at least somehow ... (not sure how yet )
EDIT: I'm gonna try an USB bootable OS first

Are there any other options to try before declaring the LAN port to be broken on my NUC?

let's see what ethtool enp2s0 has to say

I believe I can't conclude anything other than a dead card/port .. USB Ubuntu indicating 'No wired connection detected' ..

As a last resort before sending it back I thought to reset the BIOS, and guess what... Blinking lights... I have absolutely no clue why this would have worked as I haven't touched the BIOS in months...
