DSharpPlus: VoiceNextClient.ConnectAsync never returns

I’m trying to make a bot join a voice channel, but when i call vnext.ConnectAsync from a command it never returns but i can see in the voice channel the bot actually joined, so i tryed playing some audio but vnc.SendAsync never returns as well. Both my code and the example code don’t work.

All libraries from nuget: version 3.2.2 .NETFX 4.6.1 Windows 10 Fall creators update Default WebSocket client Visual Studio 2017 No exception.

To reproduce:

[Command("join")]
        public async Task Join(CommandContext ctx)
        {
            var vnext = ctx.Client.GetVoiceNextClient();
            var vnc = vnext.GetConnection(ctx.Guild);
            var chn = ctx.Member?.VoiceState?.Channel;
            vnc = await vnext.ConnectAsync(chn);
            await ctx.RespondAsync("Connected");
        }

The answer is never sent, but in discord the bot is shown in the voice channel.
