Thanks Roger - that was a palm facing moment for me... I thought I had all the ND issues with IPv6 fixed, but apparently not... those 4 were not accessible externally on V6. 

I just corrected and will see if they start registering 😊

Thanks again,

Whenever I see strange issues like this, my first thought is whether the relay advertises an IPv6 address, yet it's unreachable there.

Tor is pretty good at self-testing its IPv4 addresses, but it just trusts you that your IPv6 address works.

And then only some of the directory authorities have IPv6 support, but these days it's a majority of them, so you won't get the Running flag (i.e. won't be in the consensus) if your advertised IPv6 address doesn't work.

Hope that does it!
