Description

UPDATE: After failing in the same way for at least 10 tries, on the next attempt the problematic URL now downloads fine. My apologies for reporting an issue that disappeared all by itself with no changes on my end.

The following URL for NBC's "Days of Our Lives" fails to download (see verbose output above):

https://www.nbc.com/days-of-our-lives/video/tuesday-july-7-2020/4194114

Here is the full command line that I executed in a Bash shell on Windows 10 (ignore line wrapping caused by Github):

youtube-dl.exe -v --ffmpeg-location 'C:\apps\ffmpeg\bin\ffmpeg.exe' --format best -o 'ytdl-4194114.mp4' 'https://www.nbc.com/days-of-our-lives/video/tuesday-july-7-2020/4194114'

The same thing happens if I include switch --no-check-certificate. This may be caused by a change at NBC's end, because the previous episode can be successfully downloaded — from URL:

https://www.nbc.com/days-of-our-lives/video/monday-july-6-2020/4194113

Let me know if any additional information is needed.
