PO Installation and NWDS

Dear Experts,

We have a brand new PO Installation. After the installation according to the guide was done we wanted to connect to the CE system from NWDS using "SAP as Java" setting. We installed the latest NWDS from https://nwds.sap.com/swdc/downloads/updates/netweaver/nwds/nw/731/

https://nwds.sap.com/swdc/downloads/updates/netweaver/nwds/nw/731/

Under "SAP as JAva" Settings in NWDS after entrying the "Instance Host name" and "Instance Number" and clicking ok the popup goes away and there is no entry in the list. Also no error message whatsoever. After i had a look in "Error log" I saw this:

com.sap.managementconsole.datamodel.exceptions.UnauthorizedException: Invalid Response code (401). Server [http://qpmr-nw01.sap:50113/SAPControl] returned message [Unauthorized]. Http proxy info: none

What are we missing here?

Thanks for the helps.
