ERROR YoutubeAudioSource / Songs do not load

[Ezzocorbi]

Before

• [x] I have checked for similar issues already
• [x] My issue is not a bad syncronisation between the Spotify track and the YouTube audio (Those go here.)

Description

Songs do not load

Song

It does this with every song

Additional Information

This started happening after I have listened to about 10 different songs, I already tried changing the YoutubeAPI Key and it didn't work.

(I know there's already another issue about songs not loading but it seems like they're having a different problem)

I am getting the same issue after deploying the latest version from git. I have mine running in Docker.

I had an instance I deployed before about 7 months ago. I used the same API keys for this new deployment. If I load the audio myself via the tune menu, this works fine
