I’m trying to set up reporting services 2005 to use ssl with a 2008 instance also on the same machine also using ssl.  I’m trying to use the simple method of changing the ssl port of the 2005 site.  The website’s ssl certificate seems valid when I go to the /Reports directory, but a call is going bad somewhere inside.

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

I was directed to activate network tracing for the .net application as outlined here:

After figuring out what version of .net the application is using, which can be found in the IIS settings for the site, activating was as simple as moving the proper xml into my web.config file for the SSRS web application.

I also added this code to direct the trace output:

Now I’m seeing  the network.log file in the reportmanager directory.  I also see some calls happening to the webservice which don’t include the 444 port number which would be necessary to make the ssl connection.
