There’s a site whose content my community posts regularly, and it won’t Onebox despite being whitelisted to force it. Its OG validates on Iframely.
Here’s an example:
[https://www.roarlionsroar.com/penn-state-basketball/2018/01/3676/penn-state-vs-minnesota-preview](https://www.roarlionsroar.com/penn-state-basketball/2018/01/3676/penn-state-vs-minnesota-preview)
Sorry if my searches for a previous answer to this were unsuccessful. Any ideas? I’m running 1.9.

Usually this is because it is missing a text description. Does iframely validate the text description field?

Yeah, it does:

Sure can you take a quick look @vinothkannans?

That website returns `403 Forbidden` response whenever Discourse try to fetch the URL with request headers ` {"User-Agent"=>"Discourse Forum Onebox v2.0.0.beta1"}`. Looks like they are blocking all the unknown user agents.
