Trying to select what image is shown when site is posted to Facebook

Greetings,

I have followed the directions as written in a post on this topic, and I'm still getting an error message through the FB debugger: "Provided og:image, https://holygossip.com could not be downloaded. This can happen due to several different reasons such as your server using unsupported content-encoding. The crawler accepts deflate and gzip content encodings."

The image URL is plugged in into meta tags as <meta property="og:image" content="https://holygossip.com/x/cdn/?https://storage.googleapis.com/production-homestead-v1-0-5/285/229285/lWROCgaH/09cd59ed9d0f4ae286c1a5a4149d5155"/>

Not sure what to do next?
