Post did not publish when scheduled

Sometimes its a missed schedule. I don’t know when or why is doing it, but it’s not too often.
It’s always good to check the post if it’s published or not.

My guess is this is a CRON issue.

WordPress is relying on someone having visited the website at or shortly after 3am to prompt that post to be published.

This can be a problem on lower traffic sites.

Thanks for all the help! In this case, it was operator error. I hit Save instead of Schedule (duh). Newbie mistake. But I will keep these things in mind going forward! Thanks again for your time.
