Discord机器人无法播放更长的YouTube音频

Question

播放诸如this one之类的大约5秒钟的链接时，该漫游器可以正常工作，它会播放音频并随后对命令做出响应。

播放更长的时间后，机器人似乎无法响应命令，也不会播放音频。它不适用于代码中的YouTube链接，并且在命令提示符下也不会出现错误。

if (message.member.voiceChannel) {
    if(command === `${prefix}join`){
        message.member.voiceChannel.join()
            .then(connection => { 
                message.reply('Connected');
                let stream = ytdl('https://www.youtube.com/watch?v=Rq2vdkfjaMg', { filter : 'audioonly' }); //When joins plays a small entry sound. 
                let dispatcher = connection.playStream(stream, streamOptions);                              //Putting a longer length clip doesnt work.
            })
            .catch(console.error);
    } else if(command === `${prefix}leave`){
        message.member.voiceChannel.leave()
    } else if(command === `${prefix}play`){
        message.member.voiceChannel.join()
            .then(connection => {
                let stream = ytdl(args.toString(), { filter : 'audioonly' }); //args = youtube link
                let dispatcher = connection.playStream(stream, streamOptions);
                dispatcher.on('end', () => {
                    message.member.voiceChannel.leave();
                })
            })
            .catch(console.error);
    }
} else {
    message.reply('You need to join a voice channel first!');
