Can't acess my site through url, only by ip

I have a brand new Digital Ocean (DO) running Ubuntu 16.04 (this was a Ubuntu 16.04 with LAMP). I’ve installed Wordpress on it using the default configuration.

It’s been 3 days since my DNS are pointing to DO servers, but I can’t access my site through url, but I can access it by typing the IP on address bar.

I’ve add a A record with @ pointing to my droplet, then when I type my url it changes to my IP and I can access the site. Off course, I don’t want this configuration.

My domain is novetatd.com.br

My apache configuration file is:

<VirtualHost *:80>
	ServerName novetatd.com.br
	ServerAlias www.novetatd.com.br

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        <Directory /var/www/html/>
            Options Indexes FollowSymLinks
            AllowOverride All
            Require all granted
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        <IfModule mod_dir.c>
            DirectoryIndex index.php index.pl index.cgi index.html index.xhtml index.htm
        </IfModule>

</VirtualHost>

At DO domain panel I have only 3 records with type NS, hostname novetatd.com.br, value ‘directs nsX.digitalocean.com.’ (X from 1 to 3), TTL 1800

What I’m missing?
