Unable to setup Netlify DNS on custom domain!

Hello folks,

With regards to my site - https://avatars-ai-chat.netlify.app/
I need to delegate it to Netlify for my custom domain purchased from Namecheap.com - https://avatars-ai.chat

However, under DNS Panel settings, the status is stuck as - Awaiting External DNS
And further error says:
“A DNS zone for this domain already exists on NS1, the DNS provider backing Netlify DNS
Please contact NS1 with the domain name for support.”

Please help me out of this situation as the purchased domain is dormant due to this and im unable to resolve this out.
I already have 2 other sites published using Netlify where in I used custom nameservers from below and did the same this time as well, but it is not working :

Please help me resolved this issue at the earliest!

Hi @binaryshrey,

How long ago did you set this up? As far as I know it might take a couple of hours (for me it did).

Its more than 48h now!

@binaryshrey ok that’s way too long for what I’m concered. I’ve escalated your topic.

Thanks, hoping for a quicker resolution!
