Unable to restart setup domain

my domain says its in use. when i try to delete it says i must contact support. on github i try to link but keep getting dns error

What’s the hostname?

idk how to find hostname

What’s the domain you’re trying to add?

/overworldrad.io i own it registered to cf

Ok, I don’t see that the hostname is already in use, as it doesn’t resolve.

Where exactly are you trying to delete it?

i have no idea what im doing. now the website is finally down at least. i will try again

“/449d500f.overworld-radio.pages. dev/”

the page displays nothing. im just trying to delete it but it says its in production. i cant find how to disable production so i can delete this
