Anyone else getting a black screen that says, "Sorry -- Because of its privacy settings, this video cannot be played here"? I can't tell what it's complaining

Anyone else getting a black screen that says, "Sorry -- Because of its privacy settings, this video cannot be played here"? I can't tell what it's complaining about. I'm allowing tracking, DRM, cookies, everything I can think of. Oddly enough, I was able to easily download the video using youtube-dl, a general-purpose command-line video downloader for Unix/Linux/Windows/Mac[1]. The video was well done and informative, but I still don't understand why it doesn't play on their web page. [1] https://rg3.github.io/youtube-dl https://rg3.github.io/youtube-dl
