Error while collaborating RTC with DOORS

I'm using CLM 4.0, DOORS 9.4 and DWA 1.5. Trying to integrate RTC and DOORS.

Successfully added consumer keys to DOORS. Now in the Collaboration Links section, when I choose RTC, it gives me the Jazz login window. I punch in the username password and then I receive a blank window. I try to refresh and get the following message:

Will you allow server "<Unknown Server>" to collaborate with the server https://servername:9443/ccm/ using the "RQM" user ID?
I click on Yes and I again get a blank window.

The collaboration does not complete.
