Working in the background

Hello,
only one info, now i run the bot from orchestrator in local to remote machine linked.
In this days i have no much problem, but now all command goes in “delay expired”, i’ve tried and if i put a SendWindowMessage checked, i have no error…

what can be changed from yesterday?
may be other problems?
Machine configuration still the same
Is possible because machine is phisically off?
Thanks

Up pls
