I have a site built in angularjs and working with prerender.io and with a SSL certificate from rapidssl and everything work fine...
Except from Facebook that is not showing the right information for the page.
When I open Facebook crawler
Can't validate SSL Certificate. Either it is self-signed (which will cause browser warnings) or it is invalid.
And is not recognizing the values og:url, og:type, og:title, og:image, og:description, fb:app_id
It was working in the past, but it stop working I don't know why.
I googled and I concatenated my ssl.crt and my intermidiate.crt but without result.
My page is: https://www.granojo.com/video/10432
Your cert center isn’t providing an intermediate certificate as it should in the TLS handshake. Here is a solution how to chain your certification:
