Dear all, I need immediate help. Suddenly, all of the attended robots’ processes disappeared from Assistant and it shows “Cannot acquire a license”. In Orchestrator web panel, all of the Attended robots shows disconnected. But the other robots types, including Unattended and Studio are working fine. When I checked Event Viewer of the Orchestrator machine, I found the error below for multiple times:
UiPath.Orchestrator.Core.Exceptions.BusinessConflictException: Error code - 1420, Message - 'Cannot acquire a license.'

This is an all-new error to me and I couldn’t find any resource to resolve it. I sincerely request your help. Thanks
