Fail to add my domain name

[fatu.cn]

Account: [if0_37615556]

I try to add my domain name fatu.cn to this account, but failed, error message：
“The selected custom domain is already in use on fatu.c n . If this is your custom domain, please remove it from any other accounts first.”

But when I use Domain Checked to check this domain name, it says " The domain is not assigned to an InfinityFree account. Please add the domain to a hosting account to show a website on it."

So is my domain name fatu.c n assigned to an account or not? how can I add this domain name?

Hi and welcome to the forum! I digged your domain and it seems like it’s still in use on MyOwnFreeHost, so you might need to contact iFastNet to remove it from there before adding it on your hosting account here.
