problem with open graph tag

[shumy300]

hello, with ps 1.7 I have a strange problem since 10 days ago.
When I share a product on facebook, or if I use the scraping tool, it correctly displays the image.
I also saw the image of cms. But a dozen days ago, I no longer see the image even by scraping for cms pages.

example by product:
<meta property = "og: type" content = "og: product" />
<meta property = "og: image" content = "https://name.com/namedir/image.jpg" />

example per cms page:
<meta property = "og: type" content = "website" />
<meta property = "og: image" content = "http://name.com" /> <! - Logo Shop if no specific Image is set ->

tnx
