!!!Jog direction time-out problem when jogging robot through RWS2.0

Help!!!!I'm trying to jog the robot by RWS2.0 and it's a little different from v1.0. I made it to send the post request to the controller by postman and it worked, but the robot can only jog a little with the jog direction time-out warning: the jogging client was not able to deliver the jog direction to the Robot Controller in a timely manner.
I just can't understand...



Thanks,
Ezio
