title: Cannot play song on Heroku using Discord.js
body: <p>I cannot play music with my bot on Heroku today, its written in Discord.js.
  But I can play music very well at yesterday, I don't know what happened.(No any info in console)
  At first I thought it was an error in my code. I changed the code to the previous version and the error appeared again...</p>
  <p>I am using Node js 15 (14 has this issue too, already tried to use Node js 14)
  Discord js fork by Matte(I don't think it's Djs's problem)
  Heroku free dyno
  discord-ytdl-core 5.0.0 with ytdl-core 4.4.4(Lasted)</p>
