Facebook Open Graph not working

Hi.

Made an Facebook App and connected it to the wordpress site. Made the open graph settings. Also set fallback image.

Customized an testarticle with pictures. Set a featured image there.

Put 2 links for Custom OpenGraph images at the testarticle.

Saved everything and published the testarticle.

If i share the article on facebook i do not see the featured image, the custom Open Graph images or the fallback image. Nothing.

I spend a lot of time already and did everything accordingly to your documentation.

Whats wrong?

This is my testarticle:
