QGC Connnection problem MESH

I have problem with connection RFD(serial) with Multipoint fw3.0 to QGC. When I connect it via Mission Planner it works with some delay but works. I can’t connect throughout QGC on windows. QGC on Ubuntu works very well. I’ve tryed run as admin but same - port is open but no mavlink decode.
QGC on windows with RFD with std FW works fine.
