HTTP error 503 Service Unavailable

I am getting a very strange error that i cant seem to trap.

I am following this code from examples:
https://github.com/fent/node-ytdl-core/blob/master/example/ffmpeg.js

I am testing it out with this video:
https://www.youtube.com/watch?v=3CMp3iu7jGQ

The response i am getting from ffmpeg log:

```
