Tivoli Endpoint manager installation failed.

Issue

I am running Tivoli Endpoint Manager and utilizing that product to download patches. The question is actually related to our account.

The plugin that is used is successfully logging into RHN but attempting to search for specific packages. I am trying to determine if the URL has changed for looking up packages or if we have some other limitation in our account?
