In case someone encounters ‘unauthorized’ errors with on-prem Orchestrator related activities using UiPath.System.Activites 20.10+: In my case it was recently expired Identity Server’s token signing certificate. Updating the certificate solved the problem for good.
It was difficult to find out because web orchestrator and licensing were working normally. Thanks to UiPath’s support for identifying the issue.
