Displaying Open Graph cards on LinkedIn needs TLSv1.2

66 words, 1 minutes.

Well that’s irksome. If you share a link on LinkedIn and your webserver is secure enough to not run less than TLSv1.3, the Open Graph image won’t render.

It will look fine if tested on opengraph.dev, but post it on LinkedIn, or test with their preview page, and it will fail.

So you can either have boring links with no rich display, else downgrade your TLS.
