On a site I help run, we’ve recently found that a certain site fails to onebox (becomes a large empty space). We would have just blocked the domain from oneboxing, but that breaks oneboxing the forum hosted at a sub-domain of that site. Is it possible for us to allow the sub-domains to onebox without allowing the top domain to onebox?

For example, this main-site onebox fails (https://replit.com/@Firepup650/Yeehaw): https://replit.com/@Firepup650/Yeehaw But the subdomain (Discourse) is fine (https://ask.replit.com/t/my-intro-i-guess/20705): https://ask.replit.com/t/my-intro-i-guess/20705

unfortunately i don’t think that is possible as per this topic [图片] How can I block specific links from oneboxing? Support I’m trying to preserve the oneboxing of the homepage of a specific domain, but prevent the oneboxing of any thing more that that. i.e. mydomainofinterest.com makes a onebox mydomainofinterest.com/anything does not Is this achievable? I can only seem to block an entire domain - which would be fine if I could get the homepage of that domain to still make a nice onebox.

There seems to be something off with the link that creates the giant blank space. In the preview I notice it tries to give a big ‘Replit’ logo image. Could it be that the image used on those type of pages is breaking the onebox? Sorting that out may help them resolve nicely.

There’s a specific script for Replit oneboxes: lib/onebox/engine/replit_onebox.rb 7a204e754 # frozen_string_literal: true module Onebox module Engine class ReplitOnebox include Engine include StandardEmbed matches_regexp(%r{^https?://(replit\.com|repl\.it)/.+}) always_https def placeholder_html oembed = get_oembed HTML end def to_html This file has been truncated. show original When we paste a Replit link, the composer shows the expected result: [image] When the post is processed, the link is transformed into an empty iframe. #document I don’t know if the issue comes from Replit or from the onebox script. I’d guess it’s the script, but I’m no coder :slight_smile: The link has proper opengraph tags, though: https://developers.facebook.com/tools/debug/?q=https%3A%2F%2Freplit.com%2F%40Firepup650%2FYeehaw

I actually got it to work so that Discourse would not onebox replit.com but would onebox ask.replit.com. For some reason that only worked once though. After that it just blocked all oneboxing on both domains. Odd. [image] I help run the same forum as Firepup

After explicitly allowing Replit iframes, the following iframe code (Which seems similar to what @Canapin posted) works fine:
