Welcome to forums
Can you check if the UiPath Assistant is connected to your orchestrator?
Is it onprem orchestrator or Cloud orchestrator?

Thanks

This is happening when your login session between Robot/Studio and Orchestrator Cloud times out. You need to sign out (from Studio or Assistant) and sign in again.
