My account used to have domain name https://gitlab-aic.dynu.com/, But right now its missing the entry can I know the reason why?

Also all the other dynu.com that we set up are not working anymore. Please help us find a reason.

Thank you.

Same problem for me, maybe they just simply removed the ability to use any dynu.com for dynamic dns, because if you try to register a new dyndns you can' choose that domain?
