Issue/Introduction

Probe list is not displayed in the right pane when expanding the robot node in the Infrastructure Manager

When selecting the robot in the Admin Console, displays an error:

"Failed to retrieve information for robot at domain/hub/robot" 
" Failed to retrieve information about robot at domain/hub/robot/controller" 

A reboot of nimbus robot watcher service will temporarily fix the issue on this robot, but the same issue could happen on a different robot.

In the hub log, found intermittent errors:
