Just downloaded a fresh copy 5 minutes ago, tried it with a simple command like this:

youtube-dl https://www.youtube.com/watch?v=NK6B6WjHC68

And there ya go:

[youtube] NK6B6WjHC68: Downloading webpage
ERROR: Unable to download webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)> (caused by URLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)'),))

That's on Windows 10. All my browsers can open the url perfectly fine without warnings or anything.

Two of them as well, and both expire somewhere in 2022.

There should be exactly one. Can you check that both have exactly the name "GeoTrust Global CA"?
And, is the start time of the valid interval of the certificate covers your current system time?

I also have this issue on Linux. New cert file, openssl 1.0.2g, python 2.7.11. I also tried the 2016.03.14 version of youtube-dl, same results. It seems to be a youtube-specific problem, as CBS (Platform) works fine.

@steve5777 On Linux SSL certs handling is different from Windows. Please refer to #5225.

OK, sorry about that. In my case, the problem turned out to be a Python update. Apparently all versions since 2.7.9 try to verify certs by default. After much searching, it turns out all I needed to do was set the variable SSL_CERT_FILE to the correct location. No idea if this helps with Windows, though.

@cc0ut As another reporter said in https://github.com/rg3/youtube-dl/issues/9046#issuecomment-204344648: you need to visit https://soundcloud.com/ and https://api.soundcloud.com/ in Internet Explorer or Edge so that Windows will fetch the necessary certificates.
If things are still, check "GlobalSign Root CA" in certmgr.msc.

Two possibilities:

As Adam Goodman said in http://bugs.python.org/issue20916, Microsoft pre-installs some certificates. The one YouTube uses (GeoTrust Global CA) and the one Vimeo uses (DigiCert Global Root CA) may already be included.
A root CA issues certificates to many websites. Visiting any of them in IE/Edge brings necessary root CA certificates.

I believe @thany is also a victim of Microsoft's new policy. If anyone gets the same error, feel free to open a new issue or leave comments here.

@thany commented on GitHub (Feb 24, 2017):

But such a thing shouldn't be necessary, right?

For instance, this cannot be done on a Server Core edition of Windows which doesn't have any GUI. Furthermore, IE11 is a deprecated browser - requiring that, even if only once, feels not right.

Lastly, it's a workaround that seemingly has nothing to do with the script. I mean, why would visiting the site with a deprecated browser magically fix this script? Makes no sense to me.

But good to know there's a workaround. Because that's really what it is :)

Indeed. Another Microsoft software design with no sense.
