Ros - Robot communication - Pipeline producer overflowed

Hello. I want to control the ur10e robot through ROS.

In order to do that I installed the ur_robot_drive from GitHub - UniversalRobots/Universal_Robots_ROS_Driver: Universal Robots ROS driver supporting CB3 and e-Series. I can make the connection, however it is constantly dropping, saying the following: “[ERROR] [1605033248.263108247]: Could not get fresh data package from robot” and next, " [ERROR] [1605033251.818706222]: Pipeline producer overflowed! ".

I’m sorry if I made this report too long, but I wanted to detail everything.

I realy appreciate your help to solve this.

Thank you.
