What's the detail with YouTube videos on this instance?
If I'm on this instance, videos in a post don't render. Instead I see a big black window with this error text.

Watch video on YouTube
Error 153
Video player configuration error

You can just right click the link and go to youtube to see it, its not a complete disaster.
I do sort of need to figure this out tho. I'm doing my best to mod a music comm, so the videos are pretty important.

I've tried testing from other instances ... and there's no problem. I have accounts on eviltoast.org (regular lemmy) and moist.catsweat.com (mbin). No problem viewing those same posts from either of those instances. I didn't even notice the issue until I started using my sh.itjust.works account regularly.

It doesn't seem to matter who made the post or how old it is. When I'm logged into my sh.itjust.works account, all of the youtube posts show the black window.

I normally use firefox+adblockers, but I have sh.itjust.works whitelisted in ublock. I've also tested in my completely clean Vivaldi.

I've tested from various machines. I consistently see the empty black window only when I'm viewing these posts through the sh.itjust.works instance.

I'm a newbie mod, but this is not even a mod thing. I'm just reading a post here. Basic internet stuff. Got any help for me?

I believe this might be related to the fact that we are behind cloudflare. I notice other instances that are behind cloudflare appear to have the same issues while those that are not behind cloudflare appear to be ok. Lemmy.world appears to strip the embedded video function completely. See https://lemmy.world/post/49302693 as an example

I also noticed someone did open a github issue on the lemmy-ui repo https://github.com/LemmyNet/lemmy-ui/issues/4001

I'll take a look and see if there's something in the nginx settings that could fix this

alright, turns out it had nothing to do with cloudflare and more related to my nginx settings. I made some changes and it appears to have fixed the issue. Let me know if this has fixed it on your side as well.

Thank you

YES! It seems to work. Cool man. You got it.

Thank you.

I think it's a Lemmy-wide issue and no one's ever fixed it. Not even piefed. Even on piefed, you can't get video to play unless you click on the link and go to the post. It'll play there, but it won't play from the main page. Pretty sure the rest of Lemmy is worse.

Thanks for the response, but this is not true!

It works fine. I'm listening to it now.
