Hello,  
I ran command

```auto
roslaunch px4 mavros_posix_sitl.launch

```

then I ran a command

```auto
rosrun my_ros_package offb_node

```

offb\_node is the executable file of offb\_node.CPP, provided by PX4 website [mavros\_offboard](https://docs.px4.io/master/en/ros/mavros_offboard.html)  
then I met an error like this image:

- the program sink in the loop of changing the mode from offboard to armed
- failsafe mode somehow activating, and being deactivated, keeps going, never stop
- the plane can never takeoff  
if were any solutions. please tell me, thank you

Thanks to my senior friend LBY’s fixing, bug was solved;  
There are so many reasons to activate failsafe mode, mine is **no manual joystick**  
so I launch QGC, set using joystick as clicked, then the bug is fixed;

when it came to multi uavs, this issus seemed to happen again.  
Even though I clicked “use virtual joystick”, the plane could take off would only be uav0
