RFD900+ is connecting with MissionPlanner but not with QGroundControl

I am trying to connect RFD900+ with the QGroundControl via PixHawk 4 (Holybro).
The green light on the ground module and air module is stable, Red light is blinking.

But when I opened the MissionPlanner, telemetry successfully connected in that.
I tried to load the configurations of RFD900+ via the SikRadio tool and it successfully loaded the configurations.
