Dintle,
Since I believe we are dealing with SCCM 2012 in your environment, and please correct me if I am wrong here, I am referring to the Distribution Point for SCCM. The Distribution Point needs to be set to HTTP mode for QMX to work properly with the software distribution process. At this time QMX does not support working with HTTPS mode with SCCM 2012 for the Distribution Point.
The location of the Distribution Point settings will be in the roles section for SCCM 2012. If you require further assistance with this issue, please open a support case.
Thanks,
Jeremy Thompson
