as it turned out the problem was that the IP I was using (1:2::3:4 was
an example), had a section with leading a zero and another without.
The UEFI firmware that I was using doesn't allow this

in other words
fc00:0101::1 - Wont work
fc00:101::1 - Worked fine

I then hit another problem, but I'll start another thread about it.
