I have successfully configured RPE (1.1.2.2) to connect to data sources for all Jazz applications (4.0.x) in my environment (including some legacy such as CQ and ReqPro).  I can report on artifacts within each of these applications using the same userid and password in the configuration.  When I try to follow a linked href using a dynamic Data Source Configuration into another application (e.g., from RQM to RTC on the same Jazz Team Server -- all are co-hosted on same server), I get a "connection refused" error (details below):

Does anyone know why the same credentials that work from RPE directly to a data source do not appear to work indirectly across applications through the dynamic Data Source Configuration?
