Description of your issue, suggested solution and other information

I have been having this issue in the last couple of months. Download starts, then it stops with this error with a farily high likelyhood. One can force himself to download videos even with this bumping up over and over since it can pick up at the last byte it has been left at. Sometimes it is much more frequent than other times. Recently I managed to download a 25GB playlist in 3 tries. However now a 23GB playlist needed 21 tries to complete... Worst is when it doesn't even get to 1% of the data before it crashes.

I have seen other issues here in the past with similar error message, hence the --no-check-certificate option; I've also tried clearing expired certificates. I've seen this post linked to somewhere here, it may explain the cause of the problem if it is indeed with youtube-dl and not on my part: https://stackoverflow.com/questions/3724900/python-ssl-problem-with-multiprocessing/3724938#3724938. Any suggestions?

[MatrixAndrew]

So might it not be a multiprocessing error as the SO answer suggests? The random nature of the issue indicates something of this sort. At least I'm not alone: #14047.

[MatrixAndrew]

Issue still persists with version 09.15. "cant reproduce" - Funny because I can but reproduce it every time now ;). Impossible for me to use this software anymore. Doesn't matter if my anti-virus is on or off. I don't understand how there are no more users having similar problems to this, I have a super-mainstream Win 10 config... I need some suggestions else I'm gonna have to live the rest of my life in bitter sorrow.

does this issue date back to 2015 ?

I had a similar issue but i'm on windows ubuntu

This fixed it:
sudo mkdir /usr/local/share/ca-certificates/cacert.org
sudo wget -P /usr/local/share/ca-certificates/cacert.org http://www.cacert.org/certs/root.crt http://www.cacert.org/certs/class3.crt
sudo update-ca-certificates

Hope this helps 🥇

I have the same issue in 2019.09.12.1. Should I open a new ticket or what?

Using ArchLinux, here is what fixed it:

$ sudo update-ca-trust

Nothing else to do.

I'm on a summer 2020 release and am also getting this issue.

my 'fix'

youtube-dl -f best -o '%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s' https://www.youtube.com/playlist?list=PL8XX06eOucSzP4iZ3ONvAnG5gt8qLSI5S;

# .... and so on
# note the ; at the end 

'if it works, it's not stupid', this worked for me
