I have a client for whom embedded youtube videos are missing. They appear in composer’s preview, but when the messages are saved, they disappear. They are working fine in try.discourse.org . I tried whitelisting youtu.be and changing the URL to a youtube.com url too. Neither solved the problem. The …

It seems that the problem was that recent Discourse updates have caused my DOI resolver plugin to muck things up. (I disabled a couple other things too, but it was definitely some plugin. . . )

First of all, thank you both @neounix @Overgrow Regarding this: [תמונה] neounix: As a kludge, I have tested this (not elegant) CSS (for you) and it seems to work to stop onebox (from processing); as a kind of “hit a fly with a hammer” approach, which you could turn on and off (add and subtract…

rebake old posts count controls how many posts flagged with the various rake tasks are processed every 15 minutes.

Hi @riking , Thanks for your input. Just a quick question… how can I change that setting? Rails Console?

[תמונה] Iceman: Just a quick question… how can I change that setting? Rails Console Yo @Iceman It is a setting in the admin UI [image]

God do I feel dumb :sweat_smile: Thanks @neounix ! I can’t set it to zero, though. The UI says that the value should be between 1 and 2000000000. So I guess I will set it to 1 and combine it with your hack… that should allow me to see if the ban lifts. (Because the other options are way heavier, be…

[תמונה] Iceman: I can’t set it to zero, though. The UI says that the value should be between 1 and 2000000000 FYI … It you need to set it to zero you can more-than-likely do it with a direct DB UPDATE query (or Rails, which I cannot speak intelligently about)

Welp, no luck. Left it with value 1 and the hack to not display anything and the Ban is still up 5h later. Worst part? Obviously there is no way to contact them, so I’m just guessing ways to solve it. :sweat:

You need to be patient. It may take up to 2-3 days before the ban is lifted in my experience. Just make sure there are no further requests to that IP.. You can check if there are still rebake jobs to run. Hint is in the code (this line selects posts that need rebaking in the background limited by r…

[תמונה] Iceman: Welp, no luck. Left it with value 1 Hello @Iceman Yes, I searched the DB for you just now and could not find a table or field where that setting is stored (was not in the site_settings table) As far as your comment: … and the Ban is still up 5h later I don’t have any spe…

There’s definitely not a support page where Google explains exactly how their DoS-prevention blocking, or any related system, works.

If someone is looking for the same change, you can use a Remap instead of a rebake, which is almost instant and doesn’t make requests to anywhere.
