I am new with linux and VPS servers in general but I am now learning through building a website that runs in VPS server. Everything else goes smoothly but when I am trying to access my site from my phone (or friends phone doesn't matter) it tries to load content from /var/www/html directory even though my site is located at home/sitename/public_html. From desktop it works fine and doesn't give any errors.

In sites-available/mysite.conf everything seems right and DocumentRoot is correctly pointing to home/sitename/public_html. But when i run

apache2ctl -S

it gives me this:

VirtualHost configuration:
1.1.1.1:80       mysite.com (/etc/apache2/sites-enabled/mysite.com.conf:1)
1.1.1.1:443      mysite.com (/etc/apache2/sites-enabled/mysite.com.conf:40)
ServerRoot: "/etc/apache2"
Main DocumentRoot: "/var/www/html"
Main ErrorLog: "/var/log/apache2/error.log"

From here we can see that the Main DocumentRoot is "/var/www/html/" instead of the beforementioned correct one. Is this the reason why I can't access my sites from my phone correctly and how this could be fixed? I have tried everything that I could find from google and yes I have purged my cache always after changes but not with a success. I would really appreciate help.
