Trouble with Vagrant - "404 - Not Found"

I had same problem. I tried to restart apache from the vagrant box, I got following warning on my terminal.

vagrant@vagrant-ubuntu-trusty-64:~$ sudo service apache2 restart
 * Restarting web server apache2   

AH00112: Warning: DocumentRoot [/var/www/html] does not exist
AH00558: apache2: Could not reliably determine the server's fully qualified 
domain name, using 10.0.2.15. Set the 'ServerName' directive globally to suppress this message

Create a DocumentRoot to fix the 404 issue by creating a directory called /var/www/html


The issue is on /etc/apache2/sites-enabled 000-default file.

Apache2 is pointing to var/www/html and vagrant example to var/www just remove de /html and make a sudo service apache2 restart.
