Description
If you are experiencing any problems listed in this issue, they are known and will be addressed as soon as fixes can be identified, written, and published/pushed to a new version of Red. This issue will be edited with new information as it's available to us.
(Last updated May 04 2025. Please visit our support server at https://discord.gg/red if you need assistance.)
This information is for our latest Lavalink.jar, released in Aug 2024: version 3.7.12+red.1 and the Lavalink yt plugin version 1.13.1.
"Sign in if you're not a bot" or "This video requires login" or "This video is unavailable"
This is an IP ban that is usually resolvable by using Oauth.
"This content isn't available"
This means your Oauth account has been flagged and you need a new one.
You will need to use a managed instance of Lavalink to resolve any of these errors.
See https://docs.discord.red/en/stable/cog_guides/audio.html#setting-up-an-unmanaged-lavalink-node-on-a-remote-vps-or-server. This is not a 1:1 guide for this situation.
When using a managed install of Lavalink, you will need to pay attention to Red updates where we may update Red's Lavalink.jar or the application.yml, and integrate the changes into your own, modified copy of the application.yml.
Specific "Solutions" which may or may not work for you:
- Find a Lavalink node on the internet and use [p]llset commands to configure your bot
You will be trusting a service with your bot's IP address and your users' playback queries
You must use a Lavalink v3 node, not v4 - You can use Oauth - DO NOT USE AN IMPORTANT ACCOUNT
You must re-arrange the sources used on your application.yml so that TVHTML5EMBEDDED is first and TV is second
Follow the additional instructions at https://github.com/lavalink-devs/youtube-source?tab=readme-ov-file#using-oauth-tokens - You can set a potoken
Follow the instructions at https://github.com/lavalink-devs/youtube-source?tab=readme-ov-file#using-a-potoken - You can configure your Lavalink host to use IP rotation with an service that is not yet IP banned
You must have a /64 or greater assigned to you
A basic guide can be found at https://lavalink.dev/configuration/ipv6/
With any of these methods:
You must provide your own application.yml to:
- detail which sources the plugin will use
- provide your Oauth information
- provide the proper potoken information
- outline which rotation strategy you choose to use and your IP block(s)
See the plugin readme for more information.
