Facebook No Longer Pulling Images for Post

This is a question about Facebook and might be more appropriate for a FB forum, but I thought expertise might be found here as well.

I have a site running WP 4.2.1. Until yesterday, I could post links to my WP blog on Facebook, and the image I had associated to the blog entry (via Yoast plugin or by using the “Featured Image” functionality in WP) was pulled by FB into the post. That functionality broke yesterday.

I did my own self-help research and saw this was not an uncommon problem, and that the FB debug tool is a recommended way to discover the problem. However, when I run the tool on the page in question, it shows that everything is as it should be. The “og:image” scrape shows my image exactly as it should be and all else looks correct. I also confirmed that the image is large enough to meet FB spec.

So, according to the FB debug tool report, the image was found correctly, there are no errors, and it should be displayed by FB. However, when I scroll down to the bottom of the debug page where it shows a preview of the post, the image is missing. And, of course, if I post the link to FB, the image is missing.

I have tried multiple images, added new posts, and deleted the first problematic one, and I keep getting the same result — FB will not pull the image despite the debugger showing that it should.

The only thing I did different was to add a FB Easy Like Plugin Widget yesterday. However, when I disable the widget, it seems to make no difference.

Here’s the debug tool link to one of my problem pages:

Any suggestions?

Also, posting links to FB from sites other than my blog results in the correct image being pulled. The problem seems to be limited to my WP page.
