It said "Awaiting Netlify DNS", but now it is saying "✔️Netlify DNS", but still isn't working

Netlify site name: branch-name–ldmentessaudaveis.netlify.app
Custom domain: ldmentessaudaveis.com.br/
Error message in browser: DNS_PROBE_FINISHED_NXDOMAIN
In Netlify: It was “Awaiting Netlify DNS”, but now it is saying “:heavy_check_mark:Netlify DNS”, but still isn’t working.
I tried to use the chatbot, and look in the forum, but the solutions didn’t worked it. I have another website with the same problem. I deleted it and deployed again, but it didn’t work. And when i searched, the DNS is already up all over the world, i don’t know what is happening. Can someone help me?

The name servers are also ok.

Everything seems to be working fine. What’s the issue?
