Dydns noho.st - back to old domian name

Hi everyone,

I have a problem with dyndns. Lat week I tested yunohost and alternative arkos. When instaled firtst time yunohost I choose some noho.st dyndsn domian. Later I erase sd card. This week i want return to yunohost (arkos is very unstable) AND want my old dynds domian.

But I can not. In internet dns reslover I still see my old ip address. New ynohost can’t update new ip address. Probably my dns key is different. What I can do ? Mabay just wait and dyndns.yunohost.org relase domian name ??

Thank for replay.
