I used the latest version and the prior version (4.6.9) of robotics-backeng image in dockhub, both of than shows the same problem: Any exercise I try to enter shows the loading screen " Connecting to Robotics Backend" and never stop.

Below there is the error the happen in container

Hi @rafae900 ,

try with RoboticsBackend 4.6.18.

In addition, a new release of Unibotics will be published this week with several improvements (which requires RoboticsBackend 4.6.19).

Cheers,
