Did you go through that question?
I am going to ask you the same questions that I did in that question if you haven't.

Is the device MSFP enabled?

The usual cause of direct push failure is firewall. Something interferring with the packets that are used by the feature. If scheduled sync works, then that is a clear indication of where the problem is.
