Download from iframe.mediadelivery.net returns me Unauthorized

[devtanya]

Hi everyone, I get the next error with yt-dlp

λ yt-dlp.exe https://iframe.mediadelivery.net/7f712870-a29e-4af5-91c9-1aae7afed352/playlist.drm?contextId=93b58b49-d999-4914-8b92-da2924880f6f"&"secret=162ad9b3-4dc4-407c-8c31-f0e95ba7f6ec

[generic] playlist: Downloading webpage
ERROR: [generic] Unable to download webpage: HTTP Error 401: Unauthorized (caused by <HTTPError 401: Unauthorized>); please report this issue on  https://github.com/yt-dlp/yt-dlp/issues?q= , filling out the appropriate issue template. Confirm you are on the latest version using  yt-dlp -U

I was trying with yt-dlp and other programs like hlsdl and streamlink, but I couldn't download the following link:

referer link: https://iframe.mediadelivery.net/embed/76921/7f712870-a29e-4af5-91c9-1aae7afed352
key link: https://iframe.mediadelivery.net/7f712870-a29e-4af5-91c9-1aae7afed352/playlist.drm?con...1-f0e95ba7f6ec

From what I have seen, the video can only be played if the iframe is on the following website: https://luxxilunar.com/

So anyone who wants to give me a hand can try accessing that site and adding the following iframe:

<iframe src="https://iframe.mediadelivery.net/embed/76921/7f712870-a29e-4af5-91c9-1aae7afed352?autoplay=true&amp;loop=false&amp;muted=false&amp;preload=true" loading="lazy" style="border:0;position:absolute;top:0;height:100%;width:100%;" allow="accelerometer;gyroscope;autoplay;encrypted-media;picture-in-picture;" allowfullscreen="true" data-rocket-lazyload="fitvidscompatible" data-lazy-src="https://iframe.mediadelivery.net/embed/76921/7f712870-a29e-4af5-91c9-1aae7afed352?autoplay=true&amp;loop=false&amp;muted=false&amp;preload=true" data-ll-status="loaded" class="entered lazyloaded"></iframe>
