I’m updating my Discourse forum from 2.6.0.beta4 to 2.9.0.beta4 and I’ve noticed that when I’m trying to create a topic it doesn’t generate embeds for specific links in the new version (works in the old version) 
2.6.0.beta4:
2.9.0.beta4:
I’m pasting the same link in both versions 
How can I fix this? I did a clean install and I’m testing the new version. Neither installation has plugins, so it is not the case of a missing plugin.
The first one doesn’t seem to have created a onebox either? It should look a little like this:
I think you would need the site you’re linking to include the relevant oEmbed/OpenGraph tags for it to function properly.
This isn’t a discourse bug.
The site you’ve mentioned does not have the relevant oEmbed Tags so a preview can not be generated unless the said website actually starts supplying the necessary links.

in the meantime, I’ve moved this topic to #support
