Today, I have noticed that Facebook doesn't pull my site's OG images.

Twitter works fine, so I am not sure if it's a Facebook issue, something changed with Facebook or whatever. Yet I did a search to see if anyone else has mentioned this, and I couldn't find anything.

I have searched Google and I noticed that SSL certificate issues can be the cause, it worked fine yesterday and no server configuration has occurred. I have put in a support request with my host, however, I am wondering if IPS can suggest anything?

This is actually the second report I have seen of this today, so Im suspecting it may actually be facebook. Do you have an example?

I've just come across this:
https://developers.facebook.com/community/threads/791595499632799/

Looking at that indeed it seems you're not the only one unfortunately. 

Time to sit it out and hope Meta fix their issue.

Would you please delete my post with the link to the Facebook meta debugging tool @Marc Stridgen. Thanks for taking a look.
