Schedule not working

I set the Auto Post Schedule to check every 2 hours and the Limit checks on certain Days to 0900-2100.
I expect 1 post each day to be posted between 9-11am because the scheduler should check during that time and there are enough posts with the correct status waiting to be posted.

But when I check the Log, the scheduler doesn’t check every 2 hours. Sometimes only once per day (and of course outside the limit).

Do I have to be logged in to my site for the scheduler to work properly or do I need to change some settings inside my hosting account?

Here are the last 3 lines from my log:
