Apache reverse proxy with ssl not working

I am trying to use apache(2.4) as an reverse proxy for tomcat(7), which works fine when I use http only.

http config:

<VirtualHost *:80>
ServerName abc.domain.org


ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
   Order allow,deny  
   Allow from all  
</Proxy>


ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/

</VirtualHost>

This works completely fine.

But when I want apache to handle https its not working at all. I tried a lot of things, but I only end up seeing a plane page with "index of /"

https config:

<VirtualHost *:443>
ServerName abc.domain.org
SSLEngine On

SSLCertificateFile path
SSLCertificateKeyFile path
SSLCertificateChainFile path


ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
   Order allow,deny  
   Allow from all  
</Proxy>

ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/


</VirtualHost>

Any help or hints would be mouch appreciated.

Edit: If you need any more information, feel free to ask.

Edit2:
