Can't login jazz.net use ITeamRepository

I can logon my own Jazz Team server(version 6.0.2), but can't logon jazz.net . The URI is right and I can logon by Browser.
Exception:

com.ibm.team.repository.common.transport.ConnectionException: CRJAZ1687E Unable to connect to the server with URI https://jazz.net/jazz/. This can happen if you have supplied an incorrect URI or if the server is down.
