SSL Certificate Verify Failed (_ssl.c:600) using Windows Server 2019

[separated]

thank you for your suggestion, maurer. surprisingly it works.

I tried to download chrome instead my previous browser is firefox, just download it and try to do a simple youtube-dl command and it works.

but I still dont know why when I running a command 'youtube-dl -U' then got a message 'ERROR: can't find the current version. Please try again later' maybe it needs a sudo password.
