Description

I'm using DiscordNet in a .NET 7 project, as an API background service. As far as I understand, disconnects and reconnects should be handled gracefully by the library. However, sometimes (very often, actually) my application crashes with this error:

[16:18:15 ERR] [WEBSOCKET CLIENT] Error while listening to websocket stream, error: 'The remote party closed the WebSocket connection without completing the close handshake.' <s:Websocket.Client.WebsocketClient>

While DNet does throw this error, it should not crash your application. It could be something in your codebase that's causing it to crash, like an async void or something.
