I updated my site today (from_version: c6782e8434f404f30de8cba054dfeac004663981), and since then have been having issues with youtube embedding. The first issue I noticed is that youtu.be links weren’t generating a onebox, while youtube.com links still worked. After playing around for a bit, I disabled the “Block onebox on redirect” setting, which fixed the issue for youtu.be links, although I need to rebuilt HTML on old posts. And /shorts/ links still aren’t working, even if I rebuild the HTML. No errors in logs, nothing else I’ve noticed broken. Not sure if it’s related, but in trying to troubleshoot I also noticed that trying to disable the ‘Lazy videos’ plugin gives an error: “An error occurred: You are not allowed to change hidden settings: lazy_videos_enabled” Any ideas?

Thank you so much ! Your solution worked ! (appart for shorts…)

I don’t think there’s anything to do here on our end. All sites have SiteSetting.block_onebox_on_redirect false by default. Meta does so too, so most sites that don’t touch this setting would have youtu.be and /shorts resolving as per normal. I was concerned that either of these changes FIX: Add ld+json VideoObject to each lazy video (#34678) · discourse/discourse@a9b1fb9 · GitHub or FIX: update final destination to use more recent user agent (#34207) · discourse/discourse@4a17a31 · GitHub caused the issue, but I can confirm it did not. I did see this blog post which seems to be very timely - Google URL Shortener links will no longer be available [updated] - Google Developers Blog Any developers using links built with the Google URL Shortener in the form https://goo.gl/* will be impacted, and these URLs will no longer return a response after August 25th, 2025. We recommend transitioning these links to another URL shortener provider. While it mentions only goo.gl, I am not surprised if under the hood youtube links have also been made to undergo some sort of redirection moving forwards. For posterity, here is a youtu.be and a /shorts link rendering fine [Singapore GP 2025 | Highlights | Comedy on F1 racing] [The Twins]

YouTube Shorts don’t embed on our site either, is there a setting I need to adjust to make it work?

Do you have an example SFW short you can paste here? If private, feel free to PM me.

Here’s one for example [This may be controversial… #sims4]

Ah it works here. Doesn’t work on my site https://forum.tardis.guide Link where someone posted it but it didn’t work: [image] What Are You Currently Playing? General / off topic video-games your-current-project I know nothing about inzoi but I hate Sims 4 fans because of this kind of behaviour 😭 “Sims has lore , Inzoi has none” I don’t think it’s a fair comparison because the Sims has been around for years when Inzoi is very recent , why would anyone... (I’ve also tried posting it myself)

Do you have non-default values onebox settings? e.g. on /admin/site_settings/category/all_results?filter=onebox

I don’t have any non-default onebox settings: [Screenshot from 2025-10-14 10-38-52] It looks like some shorts work on my site, but not all. For example, @nat’s ‘The Twins’ short gets embedded properly, but @Shauny’s does not. And, not sure if this is relevant, but another difference I noticed between them is that Natalie’s shows a picture in the WYSIWYG preview and Shaun’s does not: [image] That seems to be consistent for other shorts that do and don’t embed properly on my site. Shaun, can you replicate?
