You need A Fully Qualified Domain Name (FQDN) pointing to a dedicated IP address of the webserver.
This needs to be configured by your DNS administrator or provider.
1 – Install Certbot in Centos 8
sudo curl -O https://dl.eff.org/certbot-auto
chmod 0755 /usr/local/bin/certbot-auto
2 – Configure Nginx server_name on nginx.conf
Edit nginx.conf an change the variable server_name to the same FQDN
