Problem with connect RSA 9.5 to DM app

Hi,

I have a problem with connect IBM Rational Software Architect Designer 9.5 to Design Management application. I have installed IBM Rational Software Architect Designer 9.5, next I installed IBM Rational Software Architect Design Manager Client Extension for RSA 9 6.0.2 to existing installation of RSA (screen no 1).

Screen no 1 - https://goo.gl/photos/toKQLFVYuyannaBGA

Next I’m try to create a new connection to DM app by click “Design Explorer > Create a new Connection”. I get a new window “Create a New Connection”, I’m entered server address (https://clm6.pl:9443/dm), name, user id, pass (user have admin rules in repository and all needed license) and I click finish. After I clicked finish button I get “problem occurred” window with error “An internal error occurred during: Logging into repository 'clm6.pl'.".org.apache.http.util.Args” (screen no 2).

Screen no 2 - https://goo.gl/photos/iPQSYSpuKmpSrbxN9

When I click Ok button, nothing happens, I get main windows of RSA and create new connection in folder “Server Connections” (with status “Status: Logging in...”).

Installation of CLM + DM on Tomcat with Derby database in 6.0.2 version on Windows Server 2012.
