Hello Srv Gthb, Could you plzz share a bit more detail about the issue you’re facing? If you can share your DNS setup (screenshot or records), or what error you’re seeing — would make it easier to help 
Here these 2 photos show what I’m facing my domain is celestial.qzz.io and the web is saying it’s qzz.io I tried doing what it said and it didn’t fix anything
Srv Gthb! 
You’re almost there—those screenshots are super helpful.
Vercel needs ownership of qzz.io (the root domain), not just celestial.qzz.io (the subdomain). If the root is already linked to another Vercel account, that’s why you saw the warning.
Make sure:
-
No other Vercel account currently owns
qzz.io. -
The TXT record is added under the qzz.io zone in Cloudflare, not the subdomain.
Wait a few minutes for DNS to propagate, then hit “Verify & Claim” in Vercel. After that, celestial.qzz.io should attach correctly.
If it still says “linked to another account,” 99% of the time it means another account already has qzz.io on Vercel.
I have no access to the root domain. qzz.io is a public suffix
Ah, got it—if you don’t have access to the root domain (qzz.io) and it’s a public suffix, unfortunately Vercel won’t be able to verify ownership for the root. 
In this case, you can’t claim celestial.qzz.io as a custom domain under your account because Vercel requires root-level verification for subdomains. Try to use a different domain you control where you can add the TXT record. If this is part of a shared/public service, you may need to contact the domain owner to verify it for you.
Basically, without root access, Vercel can’t attach the subdomain safely.
