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’t see any specific suspicious error in the forum logs. Could it be a timeout problem? Is there a way to specifically investigate this? Thanks in advance!

[imagen] AntiMetaman: But regular youtube links work. If they banned, wouldn’t all of them not work? Not the case, @AntiMetaman. As @codinghorror suggested above, YouTube appears to rate-limit / ban certain formats of YouTube links work where others continue to work. In my case the ‘/embed’ format of link works but others don’t. It looks like YouTube provides rate limits that are different per format. The ‘/embed’ one seems to allow for greater numbers. That’s purely anecdotal and I haven’t got any hard data on that. A few questions Are you hosting on Digital Ocean? Are you running IPv6? Have you checked that the video id is correctly formed - 11 characters? (stupid question - but you’d be suprised For a given YouTube video have you tried each of the three supported formats? - i.e. [imagen] marcozambi: http://youtu.be/ https://www.youtube.com/embed/ https://www.youtube.com/watch?v= Which worked and which didn’t? I have banged my head against this problem for weeks but managed to get a workable solution - but I really don’t understand why it works. Assuming that you’re seeing the same problem try installing the Onebox Assistant, then enable it but don’t configure it. I found I needed to bounce the server after enabling it to ensure it worked. In this configuration - which really should not work at all - my otherwise rate-limited YouTube videos (in any format) get expanded by Onebox - but I have no idea how this works. I have been discussing the issue with @merefield (the author) here… https://meta.discourse.org/t/onebox-assistant-crawl-for-those-previews-reliably/107405/36?u=bletch IF, and it’s a big IF, this also works for you, it’s not a proper fix as it’s just a quirk of method return values and shouldn’t be relied on long-term. Separately, I’ve also used the Onebox Assistant plugin as it was intended - by subscribing to embed.rocks and it works like a charm.

Can you define regular and non-regular YouTube links please.

If that is the case, why can’t Onebox convert into the one format that works before polling the data?

It could, I guess, but it’s not a ‘fix’. All of the formats appear to be rate-limited and eventually fail. Even the ‘/embed’ format failed for me after I tried to re-bake all of the YouTube embeds that had failed during a previous re-bake. Plus, I’ve only seen two experiences shared on here where the ‘/embed’ route worked where others failed - including my own. There’s not enough evidence yet, nor enough ‘sufferers’ yet to suggest making a change. Are you experiencing the problem too, @Terrapop - or are you just an interested party?

I’m an interested party as we move our popular community to Discourse soon. Just staging at the moment, it works for now, but we want to have a save setup right from the start, thus we will probably setup with Onebox Assistant to our own endpoint which will relay and cache responses from embeds.rock or if this fails, we will pull from Iframely.

Ok, so I was just playing around and I was able to reproduce it here on meta.discourse! I believe it has something to do with markdown. My youtu.be links do in fact work my forum as intended just not in the examples below. Youtube isn’t blocking my host at all. This won’t work even on meta.discourse: https://youtu.be/MLpyi-oVoI See? There’s nothing wrong with the video link. If you put the link on the next line, it still won’t work. This won’t work either: https://youtu.be/MLpyi-oVoIY You see? Now if I paste this same link here, it will work:

Glad you’re not beling blocked by YouTube. I think everything is working as it should - it’s a formatting issue. I believe that Onebox expanding needs the link to be a) at the beginning of a line on its own and b) if it is in the middle of a list it needs an additital return / linefeed before it. If you look at the raw version of your post https://meta.discourse.org/raw/153748/36 Ok, so I was just playing around and I was able to reproduce it here on meta.discourse! I believe it has something to do with markdown. My youtu.be links do in fact work my forum as intended just not in the examples below. Youtube isn't blocking my host at all. 1. This won't work even on meta.discourse: https://youtu.be/MLpyi-oVoI See? There's nothing wrong with the video link. If you put the link on the next line, it still won't work. 2. This won't work either: https://youtu.be/MLpyi-oVoIY You see? Now if I paste this same link here, it will work: https://youtu.be/MLpyi-oVoIY You can see that the first item 1. - the link appears in the middle of the line so it will not expand. The link must be the first thing on the line. And in item 2. there is only one return / linefeed before the YouTube link so it won’t expand either. If you look at the formatted version of your post you might be able to see that the YouTube link has a hanging indent… [image] …which means that markdown is still treating the link as being part of bullet point 2 so it won’t expand it. You could do this. This is some filler text This link will work as I’ve left two return / linefeeds after this line and before the YouTube link

Yea I’ll just have to learn to work with markdown and put youtube links on a separate line. My users are still getting used to it and it’s a post made by a user that caught my attention where their youtu.be link didn’t work which is what led to all this.

[imagen] bletch: If there is a rate-limit issue due to some recent change then I think other users will start to experience this during migration, re-baking of posts or perhaps just down to a really busy forum. The fact that onebox seemingly fails silently means that these issues aren’t visible until users start to complain that YouTube oneboxes are missing. Hi, I started rebaking 1M+ posts 2 days ago, and youtube previews don’t work anymore since today, so I guess my IP was banned. What is advised in this case? Should I just wait for the rebake to finish and contact youtube to see if I can be unbanned? Or use "Onebox Assistant", crawl for those previews reliably!?
