WARN: Not whitelisted


When trying to use the validator against https://fuzz.me.uk/https-now-green/ I get the WARN: Not whitelisted error and the card preview can’t be rendered.

The page contains the og:description, og:title and og:image tags, as well as allowing Twitterbot in the robots.txt file.

Is there any way to further diagnose this issue? On Facebook for example the OpenGraph information is parsed correctly.


You’ll need to specify at least one twitter:card tag to specify the type of card you want.

Thanks, don’t know how I missed that.
