DNS Alias not working

Hi there.
I’ve a website hosted working:

However, I added a custom domain: leaplane.io and it’s not working.
I actually changed the domain management to netlify, by chaning the NS value.
And the DNS propagation seems to have been completed. Checking the NS on leaplane.io resolves to netlify’s NS, however I can’t access my website from leaplane.io.

Hi, @ighormartins, and welcome to our Netlify community site.

It appears the domain name is working for this site correctly now. My best guess is delays were caused by the time to live (TTL) values in the previous NS records:

If there are other questions about this, please let us know.
