This is most likely caused by unstable networks. The problem should go away if you try again. If not, please paste full output of youtube-dl -v 1280x720.

I think when i use -i to ignore error, youtube-dl should continue download rest file rather than exit

[yan12125]

@lookis: The error indicates youtube-dl can't access the URL you provided at all, so -i won't help. Most likely this is due to unstable network.

A possible workaround is forcing a specific TLS version: #4578 (comment)

[Tankamin]

After 32 videos, i get this also: ERROR: unable to download video data: <urlopen error EOF occurred in violation of protocol (_ssl.c:600)>

Using windows... another download gave the same error after 101 videos.. :( What does this mean?

Can i resume or skip over the downloaded videos already if i didn't use the filename option? if so, how? Thanks.

My network connection has severely deteriorated this week (under 1mbps download bandwidth), and I have started to get this error. I think this is a bug? It should work with "bad" connections, too, as youtube-dl is indeed most useful in exactly these kinds of networks (that don't let you stream at all). I'm going to try TLS patch, but if that actually helps, then it needs to become a commandline option.

[NightMachinary]

I tried changing this in utils.py:

def make_HTTPS_handler(params, **kwargs):
    opts_no_check_certificate = params.get('nocheckcertificate', False)
    if hasattr(ssl, 'create_default_context'):  # Python >= 3.4 or 2.7.9
        # context = ssl.create_default_context(ssl.Purpose.SERVER_AUTH)

        context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
        context.verify_mode = (ssl.CERT_NONE
                               if opts_no_check_certificate
                               else ssl.CERT_REQUIRED)
        context.set_default_verify_paths()
        # if opts_no_check_certificate:
        #     context.check_hostname = False
        #     context.verify_mode = ssl.CERT_NONE
        try:
            print('hi :()')
            return YoutubeDLHTTPSHandler(params, context=context, **kwargs)
        except TypeError:
            # Python 2.7.8
            # (create_default_context present but HTTPSHandler has no context=)
            pass

    if sys.version_info < (3, 2):
        return YoutubeDLHTTPSHandler(params, **kwargs)
    else:  # Python < 3.4
        context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
        context.verify_mode = (ssl.CERT_NONE
                               if opts_no_check_certificate
                               else ssl.CERT_REQUIRED)
        context.set_default_verify_paths()
        return YoutubeDLHTTPSHandler(params, context=context, **kwargs)

But no luck. Still:

This SO question suggests using pycurl as a workaround to this issue:

I had this problem
ERROR: unable to download video data: <urlopen error [Errno 101] Network is unreachable>
When I eventually tried downloading a different video it was ok
