Use IPV6

[xtAngmO]

Thank you, it works. However, I have another issue: when playing a video that has two audio languages, it defaults to English. How can I set it to use a different language by default?

Unfortunately, it seems to me that the feature is not available.

[Novinity]

Use IPV6

how would you go about doing that?

Check doc

[devoxin]

IPv6 IMO hasn't been relevant for a while and I no longer encourage the use of it due to techniques like fingerprinting that make IP block discovery too easy for YouTube and will still get flagged eventually.

In your case, I would advise posting debug logs (but omit any IPs, credentials etc). You can have OAuth configured but it doesn't necessarily mean youtube-source has successfully generated an access token and is submitting it with requests.
As an aside, if logs check out OK then it is likely your IP is flagged and no level of OAuth or IPv6 rotation will help. You would need to get a new IP address and/or change hosts depending on the circumstances around the flagging.

[ERROR] This video requires login.

I should note that it works fine when i run it from my computer, just not with the hosting provider.
I'm using AndroidVr as the client.

[southctrl]

This is why reading the error is useful. com.sedmelluq.discord.lavaplayer.tools.FriendlyException: This video requires login.

[devoxin]

YoutubeAudioSourceManager - OAuth has been enabled without registering any OAuth-compatible clients. Please consult https://github.com/lavalink-devs/youtube-source?tab=readme-ov-file#available-clients

Your client list isn't being used.

[Novinity]

AndroidVr is the only one that seems to actually play anything when run from my PC, but it doesn't work when on the hosting provider. All the others give varying errors (most commonly, the "must find sig function" error)

also here is my code for registering the clients:

[Novinity]

also, i was under the assumption that AndroidVr was compatible since it has had no issues in the past and works fine on my pc

[devoxin]

If you visit the link that is in your logs, the table shows you which clients are OAuth compatible. Please don't make assumptions when there is solid information out there.

For the cipher stuff, you need to run a remote cipher server, which has instructions in the README.
