Hi, @anthony, and welcome to our Netlify community site.
There is a community “common issue” topic about this here:
We can help you make sure that all required DNS records are active and working at Netlify. What we cannot help you with is determining what “all required DNS records” actually means.
We need you to tell us what records need to be created. With that information we can assist with creating and verifying those records.
Would you please tell us what records aren’t working at this time?
(PS: @Kyliux, thanks for your input as well. DNS propagation delays are a common cause of such issues.)
