I ran this command:
sudo certbot --nginx certonly -d pabx.t3m.com.br
It produced this output:

IMPORTANT NOTES:
The following errors were reported by the server:
I tested another domain that redirects to the same server
pabx.yousmart.com.br and it worked perfectly
same nginx rule same ip as server.
My web server is (include version):
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don't know):
I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
yea
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
Your host isn't reachable on port 80 (nor on port 443 for that matter). This is required for the challenge. Please open port 80 in your firewall(s) and/or (NAT) router.
An alternative would be to use the dns-01 challenge, but that's way more difficult to set up in most circumstances.
You can't, this is not an issue with certbot. Your site isn't accessible from the world wide web at all. You can check external sites such as https://downforeveryoneorjustme.com/pabx.t3m.com.br to verify this.
Getting your site up and running for the world wide web is pretty much outside the scope of this Community I'm afraid.
