ERR_CONNECTION_REFUSED when trying to configure Apache Virtual Host

I'm trying to configure Phabricator on our server. For this, I followed the docs. When I tried to configure Virtual Host on the Apache2 server I encountered an error. I changed our DNS record for phabricator.<our_comapny_name>.com to target our server where phabricator is hosted.

I also added the file with the same name to our server's /etc/apache2/sites-enabled to define Virtual Host. It looks like this:

Listen 80
<VirtualHost *:80>
  # Change this to the domain which points to your host.
  ServerName phabricator.<company_name>.com

  # Change this to the path where you put 'phabricator' when you checked it
  # out from GitHub when following the Installation Guide.
  #
  # Make sure you include "/webroot" at the end!
  DocumentRoot /home/myuser/scripts/phabricator/webroot

  RewriteEngine on
  RewriteRule ^(.*)$          /index.php?__path__=$1  [B,L,QSA]
</VirtualHost>

And, then I added the symbolic link to sites-enabled like this: ln -s ../sites-available/phabricator.<company_name>.com phabricator.<company_name>.com

I tried restarting apache2, but I always get ERR_CONNECTION_REFUSED.

When I try to access the apache2 directly by using server's IP on port 80 I get "Apache2 Ubuntu Default Page", which I think is fine.

I also tried running "apache2ctl -V" to check which config file apache2 is using. Everything seems fine, looks like /etc/apache2 is the root dir. I don't know what else to try...I also flushed the IP tables without success
