Nextcloud conf not loading correct page

Question

I have got nextcloud working in a VirtualHost (See configuation below). When I only have on virtualhost (nextcloud.conf) enabled in Apache on Ubuntu 16.04, it works. But when I enable the 000-default.conf and the default-ssl.conf it keeps taking me to the main page not the nextcloud page. I have posted all my configuation files. I want to get the default virtualhosts working because I want to catch all urls that don't match the nextcloud config.

nextcloud.conf
