Why does Lavalink not allow to turn on age-restricted content?

[L1xa1s]

Basic Troubleshooting

• I have checked for similar issues (open AND closed), and my issue is not a duplicate. (MANDATORY)
• I have checked for pull requests that may already address my issue. (MANDATORY)
• I am using (and my issue is reproducible on) the latest version of youtube-source.
• My issue is reproducible with IPv6 rotation.
• I DO NOT confirm that this has been filled out truthfully.

Version of youtube-source

1.14.0

The search query/queries, URL(s), playlist ID(s)/URL(s) or video ID(s)/URL(s) that triggered the issue

What is your client configuration?

[L1xa1s]

What does the limited age-restricted support for the WEBEMBEDDED identifier mean? Is there any way I can include an age-restricted video?

[devoxin]

It means that the client may play some age-restricted videos but there's no known criteria on what passes, but there have been reports that some videos will work on it that won't with others.

Have a look at the entire table of clients, there are two that entirely support age restricted videos, conditionally.

[L1xa1s]

Yes, I saw it. But I don't understand how to include them in my Lavalink configuration and how to work with them.

[devoxin]

Add them to your client configuration list and then configure youtube-source to use oauth.

Once this is done, the clients will use the linked OAuth token to play videos which will, ideally, allow you to play age restricted videos.

[L1xa1s]

Like that? It just made an error "Loading Twitch main page failed" and It still doesn't work.
plugins:
youtube:
enabled: true
allowSearch: true
allowDirectVideoIds: true
allowDirectPlaylistIds: true
clients:
- TVHTML5EMBEDDED
- TV
- MUSIC
- ANDROID_VR
- WEB
- WEBEMBEDDED
clientOptions:
WEB:
playback: false
videoLoading: false
WEBEMBEDDED:
playlistLoading: true
searching: false
oauth:
refreshToken: "token"

[devoxin]

Twitch can be ignored, that's not relevant to YouTube.

Post your debug logs.
