DL10.4 / worker scheduler works weird

Hi ! I have installed server and clients. Some clients are united in a group to control their working hours through “working scheduling” . Group mode is enabled. Remote control is also enabled on all clients, But…
Some clients are being shutting down and turning on according to a schedule, and some clients are not, though they are in the same group. I can not understand why some clients don’t follow the rules

what may cause such issues ?

do they resolve to their hostnames correctly? there is an option to use IP instead of hostname if that’s easier than correcting DNS

Hi !
Yes. Using IP instead of hostname is enabled
