what is error 104?

[msm1365]

[user@dhcppc0 ~]$ youtube-dl https://www.youtube.com/watch?v=DJrMpFOOL-U
[youtube] DJrMpFOOL-U: Downloading webpage
ERROR: Unable to download webpage: <urlopen error [Errno 104] Connection reset by peer> (caused by URLError(error(104, 'Connection reset by peer'),))

how to fix it?

[ssokolow]

Try again. "Connection reset by peer" means that there was a network hiccup of some sort. (You see it all the time as a reason for disconnects from IRC chat servers)

I'm closing it as a network error. If you can watch the video on a browser but youtube-dl fails, post the output with the --verbose option and we will reopen the issue.

Assuming you can also watch the video using a browser in the same computer, what does echo | openssl s_client -connect youtube.com:443 output? If you have wget installed could you try running wget https://www.youtube.com/watch?v=DJrMpFOOL-U (you can also try with curl?.

[msm1365]

youtube for me is Inaccessible but i use browsec plugin in google-chrome to open youtube. I think for this reason can't downlod.

[jaimeMF]

We can't do anything then, you can try to use a proxy with the --proxy option or maybe there's an option on your system to use a VPN in all your programs (I don't know).

sudo apt-get upgrade youtube-dl

worked for me
