To fix these errors, please make sure that your domain name was
 entered correctly and the DNS A record(s) for that domain
 contain(s) the right IP address.

Try to add the following, inside server{}, on user nginx domain configuration..

location /.well-known/acme-challenge/ {
    try_files $uri /dev/null =404;
}

And reboot nginx… 🙂
