Apache and SSL certificate problem

Hi,

I manage to fu&% up my apache configuration and need help to fix that.

Everything works fine until I deside to install letsencrypt SSL certificate to my NAS. This is mostly because I want to use Owncloud without certification error messages when sending link to my friends and family. Some of those dont know what to do if they get cert error etc. in iPad.

I use dy.fi dynamic DNS service so I can use same fqdn all the time.

Situation now:

Using https://hostname.dy.fi opens apache default "It works" page and my certificate for hostname.dy.fi is correct (green).

Using https://hostname.dy.fi/admin gives me "Not found" page. Cert still valid (green)

Using http://192.168.0.xxx opens ReadyNas frontview. It actual add admin behind of URL so it is http://192.168.0.xxx/admin

I have install multiple apps to ReadyNas (GLPI, OwnCloud, Plex, PHP etc.) It seems that all application which use different ports than 443 opens from localnet etc. http(s)://192.168.0.100:32400/web/index.html open my Plex server but https://192.168.0.xxx/owncloud/index.php wont. I can access to my OwnCloud without HTTPS.

So it seems that I have distroy my port 443 access. Any idea how to fix or atleast how to start investicate it?
