You may be able to determine which jobs are triggering this by running: occ background-job:list.

Do you have a maintenance_window_start set value under occ config:list system?

Any warnings/errors under Administration settings->Overview?

Thank you, you helped me find a solution to this problem, it was that in config.php the value ‘maintenance_window_start’ => 1 was set, which runs from 01:00 UTC to 05:00 UTC while the server is usually disabled at this time ,I solved this problem by changing the value to ‘maintenance_window_start’ => 100, this means that tasks can be executed at any time. I hope this answer will help those who encountered a similar error
