Provide a description that is worded well enough to be understood
Attempting to download a video from adultswim.com that is behind the Adobe Multi-Pass provider login with valid credentials is failing with: ERROR: [AdultSwim] Unable to download webpage: HTTP Error 403: Forbidden (caused by <HTTPError 403: Forbidden>).
Downloading a video from AdultSwim that does not require a login to access works correctly, and logging in to watch the video in a browser also works correctly.
Provide verbose output that clearly demonstrates the problem
- Run your yt-dlp command with -vU flag added (
yt-dlp -vU <your command line>) - If using API, add
'verbose': TruetoYoutubeDLparams instead - Copy the WHOLE output (starting with
[debug] Command-line config) and insert it below
