RPI4 with. Ubuntu Server 18.04.4 eth0: link is down on first boot

[Metrea]

first time working with a Pi, but I am attempting to set up a web development server to host my projects. I require my raspberry pi to SSH into so I can run it headless. however after following the initial setup guide provided by Ubuntu, I am not able to connect to the internet through Ethernet. the physical port does not light up. I have attempted checking the cable with other pieces of hardware and everything works as intended.

I have also flashed raspbian to it as well to see if I could connect with wifi/ethernet since its easier with a gui. Wifi does work, but again ethernet does not only provided eth0: Link is down.

what can I attempt to see if its actually the board or not?

On Ubuntu you can use the command "ethtool" to check on the status of a network interface, here is an example of the output on my desktop.

 $ ethtool enp3s0
