I just installed my DiscordJS Bot on my new rootserver, I copied the files 1:1 to the server and started the Bot. The Bot starts normal but when I try to execute a command where the bot joins a vc and plays audio it says:

throw new Error('FFmpeg/avconv not found!');
      ^

Error: FFmpeg/avconv not found!

Which is weird because I have ffmpeg and ffmpeg-static installed, and the same script works normally on my PC when I run it. Any ideas why?

Edit: The only difference between the versions on the PC and the rootserver are the Node.js versions; PC: 16.6.0, rootserver: 17.4.0 (the rootserver is running on ubunu 11, and my PC on windows 10)
