Scheduling Publish Not Working

Over the last week, I had 4 articles saved to publish on a certain date and time. When the time rolled around, they didn’t publish. I went to look at the stats for the article, and the day/time were correct; it simply never published. This happened to all 4 of the articles I had scheduled to publish. I did also check to make sure my time zone was correct in settings. This happened from my Mac, using the latest version and on Chrome browser.
