Named based virtual host strange behaviour / Apache serves a deregistered site...

Hello,

I would need your support, but for this is better to describe a bit my configuration:

• Initial Ubuntu 14.04 with LAMP, including finished initial server setup (so I am accessing my server through a regular user – not root – and I am using sudo for the moments when I need root privileges)
• Apache is set up with name virtual hosts, meaning that I want to host several sites on the server using name virtual hosts
• For the main site I’ve made a set up following this tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-apache-with-a-free-signed-ssl-certificate-on-a-vps
• Initial the main site was set up in 000-default.conf but than I’ve moved it to mainsite.com.conf and I pointed out 000-default.conf to a different folder (I’ve created /var/www/droplet_html for this)
• DNS set up correctly in digital ocean

My problem is the following: one of the name virtual hosts (nvh1.com) is working correctly and points out to its directory /var/www/nvh1/html/ but when I am accessing the other (nvh2.com) than mainsite.com is loaded. nvh1.com.conf is configured similar to nvh2.com.conf! What is strange for me is that I’ve tested different configurations and I get the same behavior in following scenario:

• Main site configured as 000-default.conf or as mainsite.com.conf. It does not matter how mainsite.com is configured, when nvh2.com is called in browser it loads mainsite.com
• nvh2.com.conf registered (a2ensite) or deregistered (asdissite). I’ve tried to deregister it in order to point to 000-default.conf (since the DNS is still on, but no conf file is available for nvh2.com), but strangely Apache2 is serving still mainsite.com. I have test it with some subdomains which are registered in DNS but they are not defined in virtual hosts and they are pointing correctly to what is set up in 000-default.conf Of course the SSL certificate does not match for nvh2.com as it is valid for mainsite.com…

What am I missing or what am I doing wrong. I have the feeling that something small is overlooked somewhere as this is not normal behavior…

Here are also my configuration files: 000-default.conf
