We have an RTC 3.0 instance which is working fine except for the help system.
The https://servername:9443/clmhelp/index.jsp screen is displayed correctly, but opening any actual help topics results in a "resource is not available" error.

Using .../clmhelp/remote/remotehelp.jsp we can view the properties of the remote help which is set to:

Name: Rational Team Concert Help
Host: publib.boulder.ibm.com
Path: /infocenter/clmhelp/v3r0m1
Protocol: http
Port: 80
URL: http://publib.boulder.ibm.com/infocenter/clmhelp/v3r0m1
Status: Enabled

When I try the Test Connection button, I get the status "Connected". When I access the welcome page from my dashboard and attempt to "take a tour of change and configuration management" I get resource not available. URL in new window is:
https://myserverURI:9443/clmhelp/topic/com.ibm.team.concert.overview.tour.tutorial.doc/topics/rtcoverviewwrapper.html

Same result with other links on the welcome page. Had no issues during install and finalize process. Other users have same result. Thanks for any tips or pointers.
