For some reason, youtube-dl did not find your computer's certificate chain. Therefore, a secure connection to the server cannot be established.

I'll take a closer look in a virtual machine and get back to you.

Thank you very much! I used version 2 of bbb-dl to download the same address and no error was reported.

[C0D3D3V]

I could not reproduce your error, but I added a new option --no-check-certificate to skip the certificate checking.

[yilinwumath]

Thank you very much! Now it works well.
