Thanks again @BlackJack . It is possible I set the wrong ethernet port of the Nucleus to the new 5.1.1.1 setting. I will try it again after resetting the Nucleus tonight, and look for the second ethernet port as some people seem to have found it with the NUC at least if not the Nucleus.
I believe the USB ethernet adapter I am using is the same one that someone recommended for the NUC.

Here is a link to the one I got on Amazon, same as above:
