In my case, according to setting up a task using the task scheduler, as described in "Preventing the Task Scheduler from completing tasks when setting up updates," I had the task set to run every "X" minutes for an indefinite period of time.

Seeing the terrible "Operator or administrator rejected the request" for the result of the last run, I looked at the History tab and see the details that it "missed its schedule."


Decision
On the " Settings " tab in the task properties, I just checked the " Run the task as soon as possible after skipping the scheduled launch " box, and the problem was solved; although I also had to enter my credentials again.

Note. This started after the server was moved from the backup backup server after the hardware recovery was completed back to the original equipment. The operating system was Server 2012 R2, and the operating system was transferred to other equipment, while the repairs were carried out on the production server, but I did not notice it there - maybe there was an oversight - I'm not sure.
