A few days ago, the automatic embedding of videos from YouTube stopped working. 
Now when I copy the link, I get the following error message:

But, if I manually set up a code (like the Forum automatically did until the other day)...for a specific video it would be this code:

<div class="ipsEmbeddedVideo" contenteditable="false">
	<div>
		<iframe allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="true" frameborder="0" height="270" src="https://www.youtube.com/embed/oMDJI5_o0LI?feature=oembed" width="480"></iframe>
	</div>
</div>

...everything then works ok:

You can see the link above (that Forum didn't want to automatically embed), and the video below that shows when I manually post the code.

Has anyone else had a similar problem, does anyone have an idea how to handle this?

It would seem to indicate that when your server makes a call to Youtube, it's getting an error response back. I couldn't say more than that without investigating. You may or may not have logs in the system logs indicating the problem.

Thank you for your reply. :)

Yes, there is nothing about this problem in ACP > Support > System Logs.
For example, November 16th does not have any entries (I already had this problem with YouTube on that day), while other days are mostly rare errors, and they almost always related to the TapaTalk.

I'll restart the server later in the night when there are fewer people, who knows...maybe it'll work.
Do you have any other idea what to look for, try it?

 

From shell on your server, you can try requesting one of the URLs that is not embedding to see if an error is returned that might give you more insight, however ultimately the only other thing I can recommend is submitting a ticket so we can look into the issue.

Could be a content security policy block.

It turned out to be a problem with hosting:
