Since a few days (I’d say just after updating to Discourse 2.5 beta 5 - and continues on beta 6 - but it can well be a coincidence) embedding of YouTube videos works itermittently. After a few hours not working, it just restarts embedding OK. Since yesterday, it stopped working completely. I don’…

The browser can’t give you the real reason a onebox is failing. You need to try and make a similar request from your server.

I understand what you are suggesting, but: if I repeat the simple GET call (passing headers and stuff as expected) to /onebox?url=… i simply get the error HTML 404 if I repeat, on the server, the request that onebox does, copying it from the ruby code of youtube_onebox.rb, that is curl 'curl …

@Falco really sorry to bother you, but the lack of youtube oneboxing is really crippling the user experience of our forum. Yesterday I tried several things, such as trying to read the source code (to understand at what stage and what kind of condition could trigger the return of a 404 from onebox) …

I have the root cause: Youtube banned our IP, but it’s not clear why as at the time this happened we were not doing any massive rebake or similar. [image] Question for @Falco or @codinghorror : was the install of 2.5.0beta 5 or 6 triggering any rebake, which would have exceeded the request limit?

No we didn’t add any recent rebakes. Sound like a YouTube change, as other users complained too.

Try a proxy crawl using "Onebox Assistant", crawl for those previews reliably!

Thanks everybody for the replies. It remains unclear to me though why if I mimic the request that the onebox engine does (or at least I expect this to be the case. Is it @Falco ?) then I get a JSON response with a proper answer, and not a 429. [image] Is there another request done by Onebox that …

One curl statement is unlikely trip a rate limit? Try a series of them in quick succession? Run it in a repetitive bash script? (But not too much or you might get banned)

Well, simply trying to recook a single post with a single link to youtube gets us a 404 from onebox…

An interesting finding after a weekend of troubleshooting. This can maybe be something you want to have a look into @Falco or @codinghorror ? At the moment, reading the source code of youtube_onebox.rb , I see it supports 3 URLs from which the video id is extracted. http://youtu.be/<videoid> http…
