DNS Propagation still showing "Awaiting External DNS" status

My site is pkfmasonhill.com ( pkfmasonhill.netlify.app).

It’s been almost 72 hours since I changed the Nameservers on my hosting account and till now it hasn’t propagated. The status still shows “Awaiting External DNS” and when I click on the Renew Certificate button I get the error “www.pkfmasonhill.com doesn’t appear to be served by Netlify”.

Meanwhile, I have checked the NS records here DNS Propagation Test for pkfmasonhill.com - Explore the results and here DNS Propagation Checker - Global DNS Testing Tool and they clearly display Netlify’s DNS.

Please help resolve this as it has taken too long.
Thanks

It appears your domain is no longer pointing to Netlify.
