Px4 v1.14 firmware HITL fail

Hi everyone, I recently tried using the 1.14 firmware of PX4 for HITL simulation. The simulator is gazebo9. And I followed the steps in the tutorial to set up, but the gazebo model did not respon. QGC can successfully connect to pixhawk.
I tried using the 1.13firmware of PX4, the model plane can be control. Is it the firmware version 1.14 that does not yet support HITL simulation?
