EDIT by @unixfox: The Invidious team is aware of this issue. It appears that it affects all the software using YouTube.
Please refrain from commenting if you have nothing new to bring up. Thank you.

Describe the bug
This seems to be another block by YouTube - happens on any video, regardless of settings or instance.

Steps to Reproduce

1. Go to any video on Invidious

Logs
No logs on browser. In docker logs:

invidious-invidious-refresh-1  | 2024-06-06 22:35:23 UTC [error] get_video: PrMRuA3pd7g : This helps protect our community. Learn more
invidious-invidious-refresh-1  | 2024-06-06 22:35:23 UTC [warn] i18n: Missing translation key "This helps protect our community. Learn more"

Screenshots

Additional context
This seems to be a global update, done before 22:23 UTC. (10:23 PM.) From my brief testing, this is present throughout all instances, and regardless of IPv6 address.

EDIT: It looks like this is just rolling out throughout all servers, so some may not be affected yet.

This doesn't happen to all instances; https://inv.tux.pizza/ still plays videos.

[ggtylerr]

Interesting - I tried mine, yewtu.be, and puffyan, all of which seem to be blocked. Perhaps it's just targeting the more popular instances then?

[Laurendus]

Cannot confirm this. My private instance with two users is affected as well.

[NotARealPersonHere]

i am also getting same thing on a private instance hosted on vultr

edit it was working earlier i updated with docker pull then stopped working

chould just be timing

[ggtylerr]

Okay, it's clear this isn't global yet and it's a standard YouTube rollout. Please refrain from posting "i'm affected/not affected" comments :)

On my own selfhosted (local) instance, I'm getting both "This helps protect our community." and also a "You may have found a bug" - some of the public interfaces are affected too...

Here's the output (if it's any use) -

Edit: Also effects yt-dlp - seems that the "This helps protect our community" is a truncation of the full error message "Sign in to confirm you're not a bot. This helps protect our community. Learn more.", given that usually yt-dlp have multiple ways to download it might not be such an easy workaround:

They are probably A/B testing this, I just (programmatically) did 200 requests on my instance and roughly 1/3 of them returned this bug, the other times, the video loaded just fine.
This will most likely get worse the next days, so brace yourself for another downtime of all instances.
