Bot doesn't play anything

I ask it to play a song, it then says the song is now playing in chat and joins the voice chat. No sound is actually played then it leaves after a few seconds.

Here is what I'm getting:

[16:57:55] [ERROR] [SignatureCipherManager]: Problematic YouTube player script /s/player/28f14d97/player_ias.vflset/en_GB/base.js detected (issue detected with script: no n function match). Dumped to C:\Users\Anthony\AppData\Local\Temp\lavaplayer-yt-player-script14671743317299289783.js

I have the same problem too. Maybe JMusicBot doesn't work for YouTube now.
