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?

[ghost]

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.

[ghost]

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.

[mrbryce]

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

I am also having the same issue now. On mobile (using Termux) it is fine but on Windows it likes breaking. I used

You might want to check if it's not a problem with Windows 10 itself. I updated from 1909 to 2004 in Spring last year and I've been having similar issues globally, not just in youtube-dl where downloads using the https protocol would frequently stop and you either have to keep retrying or resuming the download manually until completion. This has been going on since version 2004 and it hasn;t been fixed yet.

[BlackWolfWoof]

I know this sounds stupid but might that also be related to another issue i had where downloads with chrome would randomly stop and i had to click continue again. If yes then welp... Thanks for bringing this to my attention. I'll look a bit further into this if it has something to do with windows

Is this just a Chrome issue or does it affect other applications? But yes, this sounds identical to the problem I've been facing for nearly a year now. I just hope we can both find some answers.

I failed to note previously that this has happened to two PCs I've owned in the past year. Just to make sure that it's not a problem with my connection, I ran the lates version of Windows 10 In a virtual machine and never had any issues despite running it on the problematic host. So it seems to only affect machines that have updated from 1903/1909 to 2004/20H2.

I tried several things already such as turning off my anti virus, resetting chrome, using a different browser and other stuff. I also tested it on save mode with network drivers enabled and thats where both (chrome an youtube-dl) worked without any issues.
So yea a windows issue could be the reason. I'll search a bit around today and see if i can find more info about this

[BlackWolfWoof]

@BritishDudeJon I found the issue. I am still looking how to fix it.

1. It has nothing to do with youtube-dl
2. I am using a "FRITZ!WLAN USB Stick AC 860" and by using USB-Tethering and sharing the internet from my phone this issue was resolved.
3. That means it has to do something with my network controller???? or my wifi usb stick (fun fact: in windows save mode it works fine, even with my wifi stick lol)
   I will keep you updated on what worked on my end when i find a fix.

[BritishDudeJon]

2. USB-Tethering

Nice. I'm connected directly the router via a USB wifi adaptor. I did check the event viewer to see if it was logging thses errors in some way and I did find that it was logging an excessive amount of TLS errors reading "A fatal error occurred while creating a TLS client credential. The internal error state is 10013." which from what I've read might be related to the problem. I also noticed that I am least likely to get connection drops when I my PC has only recently been rebooted. about 15-30 minutes after is when the problems start happening. Let me know if you're getting these errors too.

[yazan-abu-obaideh]

If you're having the same issue I was having, I think I've managed to resolve it using this tweak tool:

https://www.speedguide.net/downloads.php

Just use 'optimal settings' and everything should work just fine.
