DNS verification error while adding Custom Domain

[Parth Desai]

Hello,

I am trying to add custom domain to my Firebase Hosting and I get below error:

Hosting's DNS request failed; contact your DNS provider for support

I did contact my DNS provider and they confirmed the error is not on their end. A and TXT record are configured correctly. Any suggestion what the issue might be?

I do have other custom domain(s) linked to the project with the same DNS provider and they are working fine.
