Hi,
A few months ago we've a moved our Mercurial server (vm) to another network. Since then the access to our Confluence server (vm) started failing. On our Mercurcial server we found the following in /etc/apache2/sites-enabled/default-ssl:
ProxyPass /confluence http://ros3e19.dom.3e.eu:8080/confluence
ProxyPassReverse /confluence http://ros3e19.dom.3e.eu:8080/confluence
So we figured we'll just access the Confluence server directly via that url https://ros3e01.3e.eu/confluence/ but it redirects back to the Mercurials server on https://ros3e01.3e.eu/confluence/ which opens this page :
ros3e01.3e.eu uses an unsupported protocol.
