Facebook isn't scrapping meta data

It is strange, because if I go to facebook debug tools, I can see that images and all meta data is scrapped, when I paste Url on FB, it can't scrap any info, no images, no text, just showing my link. The same problem is for all my sites. I've tried pasting some other website link and FB scraped that link good.

Previously it was all good and suddenly this happened.

Any ideas on this?

That's strange. Try appending something after url to see if it changes, like site.net/page-df-d-d22?hduhdu
What happens after you actually post your link? Maybe its browser error..
