[Twitch]Download subscriber-only replay

[endorphin-pk]

I'm a subscriber to this channel. I tried to download this video but it was rejected with an error. The commands I have written are as follows.

sudo youtube-dl -f bestvideo+bestaudio -n https://www.twitch.tv/videos/661020583

And an error message.
