Access virtual host using another device (no replies)

I am trying to view my site on other devices, mainly mobile devices. I am using Wampserver 3.0 with apache 2.4.17. I am also using the virtual host feature built in wampserver to view my site and my code is not in the wamp64\www\ folder, instead it is in my documents folder. I have been able to allow other devices view the wampserver default page but whenever I go to my website i get "fitly's server DNS address could not be found"

Here is the httpd-vhosts.conf file

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot C:/wamp64/www
    <Directory  "C:/wamp64/www/">
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

<VirtualHost *:80>
    ServerName fitly
    DocumentRoot c:/users/juan/documents/fitly
    <Directory  "c:/users/juan/documents/fitly/">
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>
