Hardware in the Loop HIL not communicating with xplane

Hi all, I have just joined the community.

I am trying to setup a HIL with QGround and Xplane 10. I followed the instructions here https://pixhawk.org/users/hil . This docuemntation is quite old and QGround is very different. I managed to get to the connect step, but when I do the system stayl like that without ever finishing the connection process.

I was wondering someone can help me or point me to a more up to date documentation.

Worth notice updated the frimware to the latest PX4 available.
