Hi mahatherjoy,
One of the important points I would like to highlight is that the scheduler is triggered by the application server.So the schedules are triggered based on the time-zone configured in the application server.Also, please check the following .
1.The scheduler is enabled in system->scheduler section .
2.The scheduler is not disabled in the application server.
You can check the reason why the schedules are failing by referring to the recent activity section as is seen in your screenshot.The logs would tell the reason for schedules not running.
