RobotStudio event

maximum number of clients connected to the robot

Hello,
I have a problem to connect RobotStudio 5.61.02 online to the robot. It says that the maximum number of clients. On the robot are connected to two users and third to join. Somewhere here to read that is set in a robot maximum number of clients, to four. It can be somewhere Altering ?? Although we only connect three clients, but even so I wanted to try.

thanks
