Description

I just setup youtube-dl within the past hour so I could download videos from the Food Network, so my setup is pretty fresh.

I run the following command:
youtube-dl --config-location "/Users/Joe/youtubedl/joe-youtube-dl.conf" https://watch.foodnetwork.com/tv-shows/haunted-gingerbread-showdown/full-episodes/calling-all-ghostbusters

and I get a 401: Unauthorized error.

I am saving the cookie file using Firefox 70.0 on my Mac OS 10.15.1 using the cookies.txt extension.

I did notice in the logs that "discovery" was mentioned and I realize that the interface is identical between the two websites. Also, I came across Issue #21810 that had the same Unauthorized error for Discovery that never went answered (#21810).

My config file has the following flags:
(pound to comment) Save all videos under Movies directory in your home directory
-o '/Users/Joe/youtubedl/%(title)s'

(pound to comment) Download best mp4 format available or any other best if no mp4 available
-f "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best"

(pound to comment) Cookie location
--cookies "/Users/Joe/youtubedl/cookies.txt"

I selected my cable provider on Food Network's Webpage UI and I was able to start watching without entering any credentials. Assuming I already had the valid cookie, I exported them all to the file I reference in my config file. Is this an actual, old bug or is there someway I can authenticate myself?

@tv21 you're issue is different than the one reported here and it's related only to python 2.

@Demasterpl most likely the cookies you have exported are incomplete or expired.

[tv21]

@remitamine You are correct and thank you! Forcing the use of Python 3, along with a cookies.txt file, was what was needed for my issue (but unfortunately not the issue here).
