Looks like Netlify’s name servers are not configured and ui-dns.com name servers are. To use Netlify DNS, you’ll want to configure the name servers mentioned here.
Currently, I do see an A Record for quranplayermp3.com
host quranplayermp3.com
quranplayermp3.com has address 75.2.60.5
and a CNAME Record for the www subdomain:
host www.quranplayermp3.com
www.quranplayermp3.com is an alias for quranplayermp3.netlify.app.
Please review this Support Guide on inactive DNS Zones:
The guide explains what an inactive DNS zone is and how to resolve the issue.
If you instead want to use an External DNS configuration, you’ll want to remove the Netlify DNS zone as mentioned in the guide.
