[Arte] Video download fails. Am i doing it wrong? Why does it error out?

• I'm reporting a broken site support issue
• I've verified that I'm running youtube-dl version 2021.12.17
• I've checked that all provided URLs are alive and playable in a browser
• I've checked that all URLs and arguments with special characters are properly quoted or escaped
• I've searched the bugtracker for similar bug reports including closed ones
• I've read bugs section in FAQ
  Could not find FAQ, as https://github.com/ytdl-org/youtube-dl#faq was not working

I do not understand intricacies of web communication, thus could not investigate further.
BTW: I do connect via a VPN regularly, generally, this does not cause problems, also not with youtube-dl.

WRITE DESCRIPTION HERE
After watching this, i wanted to grab it (download), but youtube-dl could not. Usually, it does. i cannot tell the difference.

If you don't have GitHub's JS enabled, the FAQ link needs to be https://github.com/ytdl-org/youtube-dl#user-content-faq. However the FAQ can be found from https://github.com/ytdl-org/youtube-dl by searching in the page, if the anchor link fails for any reason.

I've searched the bugtracker for similar bug reports including closed ones

And yet not found any of the ~10 issues mentioning Arte that are duplicates of this, such as #30919.

... Usually, it does. ...

Do you mean, say, 9 months ago? Or now, but with other sites?

Thank you, friend dirkf, for your hints.
Yes, i forgot to reenable JS on github. And yes, after providing the links to video+audio files, i could download them and have ffmpeg make a single file from them. => successfully worked around the issue.

Thx again.
