I'm seeing "just a moment" in the first box below article title

Hi, I'm relatively new to Lemmy, but I have been posting a lot in the last few weeks.

One thing I see when I post certain website articles is the above message. The post still works, but it is missing a lot of information that other posts have.

Does someone have a link to documentation of what Lemmy is looking for when it builds a post? I would like to be able to contact the web admins of the problem website, and ask them to modify their code so that it is more "Lemmy-friendly".

Thanks for any help you can send my way.
