Preview link not showing


When entering a link from a website in the Quick Post area it will, if it can, create a preview snippet of the webpage like you would see on Facebook or other social medias. Our website allows Facebook to fetch a preview but not Telligent. Any idea what exactly is being used to bring in this snippet?

Open Graph tags have been setup, is there another area where there might be some security setting that needs to be enabled to allow Telligent to bring in the preview?
