Run the below command in a powershell.exe console in the Robot machine and then restart the UiPath Robot service.

  • Make sure that your unattended robot is logged out not disconnected when you are running the job.
  • Try to play in the Orchestrator → Robot settings LoginToConsole set to Yes/No.
