Roon Nucleus Connection Problem Ethernet Adaptor

My original setup that worked fine was connecting my Roon Nucleus from an Ethernet connection on my router directly to my Roon nucleus

I have moved addresses and am no longer able to connect my router via Ethernet directly to my Roon Nucleus. I am now connecting it via Ethernet on the nucleus thru a Ethernet to USB converter which does not seem to work. Is this not supported and the only way to connect is a direct Ethernet to Ethernet connection?

It has to be a certain type, USB 3, gigabit capable. Do you have proof (i.e. connecting a monitor) that the Nucleus is actually booting?

Did it have a fixed or reserved IP address before the move? If it did there is a process to reset that.
