"Activity timeout exceeded" error (#1680) for an unattended robot in the browser

Hello. I have a robot which opens browser and clicks on visible elemens. That robot installed on Windows Server and runs w/o any error while im in rdp session. But when i log off rdp session and try to run robot from Orchestrator an error #1680 pops up. In Job Details i get that info about error:

Activity timeout exceeded

RemoteException wrapping UiPath.Core.Activities.ActivityTimeoutException: Activity timeout exceeded
at UiPath.Core.Activities.ScopeActivity.OnFaulted(NativeActivityFaultContext faultContext, Exception propagatedException, ActivityInstance propagatedFrom)
at System.Activities.Runtime.FaultCallbackWrapper.Invoke(NativeActivityFaultContext faultContext, Exception propagatedException, ActivityInstance propagatedFrom)
at System.Activities.Runtime.FaultCallbackWrapper.FaultWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)

I read all the topics on forum about error #1680, but nothing helped me.
Can anybody let me know whats wrong?

Srini84, thank you for an answer.
I did everything from your post except fifth paragraph:

5. Restart uipath [robot](https://docs.uipath.com/robot/docs/introduction) services (Run -> services.msc -> Uipath [Robot](https://docs.uipath.com/robot/docs/introduction) -> Restart)

Maybe because I work with UiPath Studio Community, not Enterprise, i dont see UiPath Robot Service. Am I right, I should run UiRobot.exe from that location: C:\Users\Username\AppData\Local\Programs\UiPath\Studio to start service manually without Enterprise license? But execution UiRobot.exe doest start UiPath Robot service, unfortunatly
