Issue with Subdomain Verification (was previously working)

[hdanielo]

Hello Vercel team,

I’m having trouble re-verifying a subdomain that was working fine before.

Here’s the situation:

• My root domain kbklub.org is managed under another Vercel account (kbklub1).

• I have a project called yptgl-web-v1 on my account (hdanielo) that uses the subdomain yptgl.kbklub.org.

• This setup used to work perfectly — the subdomain pointed correctly and the site was live for several months.

• Around September, I noticed the site was no longer reachable.

• I deleted the subdomain from the root domain’s Vercel account and tried to re-add it to my project.

• Now, every time I try to verify the domain, I get the message:

  “This domain is linked to another Vercel account. To use it with this project, add a TXT record at _vercel.kbklub.org to verify ownership.”

I’ve attached screenshots of:

1. My project’s domain configuration (yptgl-web-v1) showing the verification message

   

2. The root domain’s Vercel DNS settings

   

Could someone please help me get this reverified?
It worked previously without issue, and I believe the DNS is set up correctly — but perhaps something got stuck in propagation or ownership linkage.

Thank you!

You can also use v0 to narrow down the possibilities.

I have tried all possible suggestions, still not working

Looks like you tried to set the DNS records in your Vercel dashboard, but the domain uses NameCheap nameservers. You need to set the DNS records on your NameCheap dashboard.

NS check:

CNAME check:
