I can still use RSSHub to subscribe: https://rsshub.app/youtube/channel/UClOGLGPOqlAiLmOvXW5lKbw

It also supports more features: https://docs.rsshub.app/routes/social-media#youtube

In some other threads people write that invidious also may have problems. Eventually any bot can have problems when reading RSS feeds. Maybe the ones with API key will not have problems. Reddit: https://www.reddit.com/r/rss/comments/1aduw8j/did_youtube_ki...

Status: Won't Fix (Infeasible)

Unfortunately, there's nothing we could do here if it's the anti abuse mechanism that prevented the call to happen.

Also, this tracker isn't meant for that RSS issues. This issue tracker is mainly for Youtube APIs described in the link below:

... and you need an api key, if you want to run that service yourself

I am seeing 404s for YouTube’s RSS feeds. I hope this is a temporary bug.

Either it is a bug, or start of a cat-and-mouse play.

I can switch to rss hub app, as suggested in a other comment, but I do not know how long this workaround will work.

Eventually every solution will stop working, if that is the desire of our corporate overlords.

I confirm. Now I see 404s now.

Seeing the same thing here. I'm also hoping this is a temporary bug. If not, I guess I'm done w/ Youtube.

You can try openrss by navigating to the user profile and adding openrss.org in front

Can you can use an Invidious instance's RSS feed or are they tied to Youtube's?

They are tied to YouTube's, I believe.

I am also trying to sub using RSS and I get no response. Odd times for sure.

Seems to have been temporary, everything's working again now.
