Description

There is a problem with streaming audio when you are streaming for a long time. Using the audio streaming tutorial as an example, if you broadcast a radio station instead of streaming a file, a series of errors occur over the course of several hours, canceling and blocking a future stream. After transmission hours an error occurs The remote party closed the WebSocket connection without completing the close handshake. This error is followed by The server sent close 4006: "Session is no longer valid." After these errors, if you try to reconnect to the voice channel using the voiceChannel.ConnectAsync() method, it throws the System.TimeoutException: 'The operation has timed out' error, which prevents you from reconnecting until you restart the bot.

I am assuming this would close the PR #2765 correct? @josago97

If so, link this bug within the PR with closes tag and if/when PR is approved this will also be closed.

josago97 commented 1 year ago

No, that PR doesn't solve this problem. When I was trying to solve this problem I noticed that the discord heartbeat was not being used and that is why I made the PR. As I have been testing, I think this problem has to do with a bad connection closure, in such a way that when it reconnects it gives an error due to residue from the previous disconnection.
