HTTPError: HTTP Error 500: Internal server error

The error itself is thrown by fragment 1350 which returns HTTP 500 no matter what. This problem is very similar to what is described in #12593. However, using --skip-unavailable-fragments did not help and the process ends.

Did you ever get this working? I seem to be seeing this problem also.

[scholtzm]

Never got it to work.

Eventualy I sent an e-mail to Ceska Televize and they fixed the issue with fragment 1350 on their end. 😄

[ankenyr]

Weird, I used -f u'bestvideo+vestaudio/best' and that worked from the command line. This was for Youtube though

I think this ticket should be closed as well, we don’t have a way how to reproduce it as the situation has changed (youtube-dl 2020.01.01 can download the show without a problem).
