Vagrant Phalcon With Subfolder VHost Problem

Hi guys, need some help. I was following this step https://github.com/phalcon/vagrant It works, I can access phalcon dashboard, virtual data sync well with local. My problem exist when I want to create project called stevelsa with dev-tools. After enabling vhost stevelsa.conf, I can not access /stevelsa form browser. In fact that I can not access the root directory too. I had enabe the site using sudo a2ensite stevelsa and restart apache.

Did I do something wrong ?

<VirtualHost *:80>
DocumentRoot /vagrant/www/stevelsa/public
ServerPath /stevelsa/
</VirtualHost>

<Directory "/vagrant/www/stevelsa/public">
Options Indexes Followsymlinks
AllowOverride All
Require all granted
</Directory>
