XF 1.5 Link forum thread on Facebook

#1
Whenever i post a forum thread link to a secret group on facebook, the facebook preview always comes up with an error. I know that Facebook cannot get the information about the link since my forum is for registered members only.
My question is simple, is it possible to have a default thumbnail and the breadcrumb text of the site for the link preview on Facebook, but when you click it, you get redirected to the actuall link that was shared?
I tried to google my problem, but the only thing close i got to was point 7 in this thread: https://xenforo.com/community/threads/frequently-asked-questions.5183/#post-180456

Edit: Added picture of a shared link on FB. "Feilmelding" translates to "Error message"
