Level 3 support linked me to a developer forum but I figured it out before they could respond.
I believe it was a driver issue as first asked by @aibd. If you look HERE Motorola doesn’t list drivers for a Linux box. I booted into MacOS and the terminal did return the key for Motorola’s website. I submitted the key and received an email back with the OEM unlock code. Hope this helps someone else out there. Thanks to you both.
