I have a fully functional OC instance running on https (443) but recenly, I have a need to run OC on an non-standard https port. I chose 8090 and made the following changes but I do not have a functional OC setup at the moment:
<VirtualHost *:8090> DocumentRoot /usr/share/webapps/owncloud ...
If I browse to https://mydomainname.com:8090 I get the expected "Access Forbidden!" message but if I browse to https://mydomainname.com/owncloud:8090 I get "Site can't be reached. mydomainname.com unexpectedly closed the connection." Please see the next post as I am a new user and cannot post more than 2 urls at this time.
