Image does not load for page with og tags when first pasted into facebook

Question

I have a page https://pixit.im/AAC It contains the video and has the correct og tags. OG Debugger says that everything is fine with him and shows the image from og: image there.

However, when I first paste this link into facebook, I do not see the image in the preview, only the text form og: title and og: description.

If I open the url in the FB OG debugger or paste it later or send an entry to this link, an image will appear.

But the fact is that every time I first insert some link from my resource ( https://pixit.im/A **) to the FB share dialog box, it does not load the image for preview. The question is why?

Answer 1

Turns off the answer also to set og:image:width and og:image:height .

(In my own testing, I found that setting og:image:width and og:image:height sufficient. Installing og:image:type not needed.)
