I installed Ubuntu 20.04 Server on my 2014 Macbook Pro and it all works great with the USB to ethernet adapter. However, when I try to use the Thunderbolt 2 to ethernet adapter I can't get the network connection to work. Running
ip a shows (what I think is) the Thunderbolt interface (ens9) as DOWN, so I ran
sudo ip link ens9 up. Then the Macbook shows up as a device in my router, but I still can't access it (have a web server running on it that works fine with the USB adapter). Running
ping google.com gives:
ping: google.com: Temporary failure in name resolution.
I haven't installed any drivers, just simply plugged in the Thunderbolt adapter and booted up. Would be very happy for some help to troubleshoot. Thanks in advance!
cat /etc/netplan/*.yaml gives:

sudo lshw -C networkwith the Thunderbolt dongle plugged in. Do you have Access Control enabled in your router? Start comments to me with @heynnema or I'll miss them.
