Why does the Confluence UI not display images and the skin correctly when using Apache/SSL

[Christoph]

I have installed Confluence on a Ubuntu box. The default config (using Tomcat directly on 8090) works fine. But the config with Apache and SSL fails because only links and basic HTML elements are visible. The skin (colors, frames, menu, layout, etc) is missing.

Here is the config:

<VirtualHost *:80>

ServerAdmin webmaster@acme.de

ServerName acme.de

Redirect / https://acme.de/

RewriteEngine on

RewriteCond %{SERVER_NAME} =acme.de [OR]

RewriteCond %{SERVER_NAME} =hostname

RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

</VirtualHost>

<IfModule mod_ssl.c>

<VirtualHost *:443>

        SetEnv RAILS_ENV production

        ServerAdmin webmaster@acme.de

        ServerName acme.de

        # DocumentRoot /var/www/html/

        ProxyPreserveHost On

        ProxyPass "/confluence" "http://localhost:8090/confluence/"

        ProxyPassReverse "/confluence" "http://localhost:8090/confluence/"

        ProxyRequests Off

        <Proxy *>

                Order Deny,Allow

                Allow from all

        </Proxy>

        <Location /confluence/>

                Order allow,deny

                Allow from all

        </Location>

        ServerAlias acme-online.de

        SSLCertificateFile /etc/letsencrypt/live/acme.de/fullchain.pem

        SSLCertificateKeyFile /etc/letsencrypt/live/acme.de/privkey.pem

        Include /etc/letsencrypt/options-ssl-apache.conf

</VirtualHost>

</IfModule>

        <Connector port="8090" connectionTimeout="20000" redirectPort="8443"

                   maxThreads="48" minSpareThreads="10"

                   enableLookups="false" acceptCount="10" debug="0" URIEncoding="UTF-8"

                   protocol="HTTP/1.1" scheme="https" proxyName="acme.de" proxyPort="443" secure="true"/>

The two proxy pass lines should not have quotes and the proxies should be consistent - all terms should end with or without a /, don't use a mix of them.  Please fix those and retry it.
