Hello, I am trying to create link previews for this site on our Discourse instance:

> **[Lukáš Němčík (COOP): Letos budeme mít až stovku automatizovaných prodejen -...](https://www.lupa.cz/clanky/lukas-nemcik-coop-letos-budeme-mit-az-stovku-automatizovanych-prodejen/)**
>
> Na naše automatizované prodejny se jezdí dívat konkurence ze zahraničí, říká Lukáš Němčík ze skupiny COOP. Je to důkaz, že naše řešení je životaschopné,…

As you can (hopefully) see, the onebox works here, but on our instance it does not:

Oneboxes for other sites work fine. What could be the problem, apart from the target website blocking us for some reason? How can I troubleshoot the problem?

maybe have a look at your forum’s various onebox settings go to `admin-settings` and type “onebox” in the settings filter box at the top. Have a look at this topic:

That’s my guess. If you have lots of links to them you could be rate limited. If they look right in preview but not when the post is rendered, this is the issue.

I’ve asked them about it and they are not blocking us. The link is not oneboxed in preview nor when the post is published. Is there somewhere I can peek at to see the particular error?
