Can you show me your LavalinkManager.init() Function / what you put in the ManagerOption#client property?

[nightnai35p]

client.user

[Tomato6966]

Can you show it to me, i asume that client.user.username has characters which are not useable in a header Make sure that your client.username does not have special chars which are not sendable.

[nightnai35p]

[nightnai35p]

Well I don't know what the error caused, nor when the error happend. But it seems like it couldn't build the connection (websocket) to the lavalink server.

You sure that your lavalink server runs on v4?

[Tomato6966]

I'm closing this now, try to do the following: Use lavalink's .jar version: beta v4 aka beta latest Use the latest lavalink-client version
