Unable to download ... urlopen error [SSL: CERTIFICATE_VERIFY_FAILED], macOS 13.1, Py3.10

[RaspChris]

Hi,

It seems to me that since upgrade of my system (and youtube-dl) youtube-dl doesn't work (always same message).
Thank you for looking into that.

Work-around: --no-check-certificate (but then, obvs, the certificate is not being checked).

Solution: update the certificates used by your Python installation. Review #31189, also pytube/pytube#241 (comment).

[RaspChris]

thank you,
I updated pyhton, I updated pip, I updates certificates

I still get the same message from youtube. Sorry

It's nothing to do with yt-dl and everything to do with how your Python and OpenSSL are installed on your new macOS. The linked issues provide guidance. Also here.

Otherwise, another work-around is that you can now install Linux on your Mac ...

youtube-dl version 2020.11.26 doesn't have this problem but youtube-dl version 2021.12.17 does, and it seems so does the latest versions.
I've tried using python and windows exec, but get the certificate error even with --no-check-certificate unless I use the 2022.11.26 release.

Show the verbose logs of these cases.

youtube-dl version 2020.11.26 doesn't have this problem but youtube-dl version 2021.12.17 does, and it seems so does the latest versions. I've tried using python and windows exec, but get the certificate error even with --no-check-certificate unless I use the 2022.11.26 release.

How can we get on the older versions ?

[dirkf]

They're all on the site, but don't bother unless your aim is to provide these test results as asked.

Show the verbose logs of these cases.

Old versions will fail in numerous other ways, so this is only useful to diagnose if some change in the HTTPS code has had an unexpected result

If you do this, also note and report your installation log for each version, in case there is some issue not shown in the program's verbose log.

I lay odds of 100:1 that this problem is due to the certificate configuration for the version of OpenSSL used by the Python that is running yt-dl being broken. The previously provided links apply.

For a usable yt-dl version, get the git master, or one of the other solutions suggested for #31350.

This old issue 5317 has some possibly useful info.
