Newbie Here PX4 + FTr10 reciever

Hello! Need help, I have a hexacopter build, all the servos plugged into the receiver work with transmitter, but can’t get it to arm. The current connection from the flight controller to receiver is from the RCIN to the servo pins on the FTr10?

Are you connected with QGC and do you see any messages pop up? Usually when you can’t arm, something is not right and prevents arming.
