Unable to download JSON metadata: HTTP Error

[rutzor]

I'm on the latest version. The issue only occurs when I attempt to embed the soundcloud thumbnails into the audio files.

When attempting to download a soundcloud playlist, I'm met with:

D:\Downloads>youtube-dl.exe --verbose --playlist-start 195 --embed-thumbnail -o

Works fine for me, looks like a temporary error.

Closing since no response for a long time.
