I use the Cubes to stream from Ethernet only out of 16 different schools each year for an educational course. I haven’t gone directly to Youtube, but some of my cameraman have that I used it in the field. Are you using the Wirecast software or the Cube? If you use the Cubes software it will stream directly to Youtube live.
select live internet streaming, then YouTube live in the dropdown menu for service provider.
I know this is a really late response to the question, PM me if still need assistance.
I hope you worked it out!
