@discordjs/voice not working in Digital Ocean app container

Issue description

I’m having trouble creating a @discordjs/voice player

My problem is the code works fine when run locally, or in Docker container on my machine, but won’t run in a Digital Ocean app

As I mentioned it works as expected running on my machine, or in a Docker container on my machine, but fails silently in a Digital Ocean app container. It feels like this will be an utter pain to debug - hoping somebody here has some insight
