Fresh install of debian, Can't get apache to work

I had to reinstall Debian. Before the reinstall I have been using my server as a file share (using Owncloud). After an reinstalling Debian on a freshly formatted drive and installing apache2 I have been unable to get the default page to show up.

Apache service is running:

    ● apache2.service - LSB: Apache2 web server
   Loaded: loaded (/etc/init.d/apache2)
   Active: active (running) since Mon 2016-08-08 14:39:45 UTC; 10min ago

If i run apache2 -t this is what I get:
