My OS is Ubuntu 14.04 and Apache version is Apache/2.4.7. Openstack version is Icehouse.

I am trying to enable https for Openstack Dashboard using self signed certificates.

I have followed this guide on configuring Apache: http://docs.openstack.org/icehouse/co...

Following this guide leads to 2 errors:

First there is something wrong with redirection. Connecting to http://mysserver/horizon (The index page of Horizon service) gets redirected to https://myserverhorizon. The slash between servername and page name is missing.

If I manually enter the correct address (https://myserver/horizon) I get warning about my self signed cert. So it seems that certificates are ok.

After accepting my certificate I get Apache error page:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

I get same error for static index page at document root so it seems that Apache has totally ceased functioning.

/var/log/apache2/error.log has errors like this:
