Feature request (request for a new functionality)
Question
Other

If the purpose of this issue is a bug report, site support request or you are not completely sure provide the full verbose output as follows:

Add -v flag to your command line you run youtube-dl with, copy the whole output and insert it here. It should look similar to one below (replace it with your log inserted between triple ```):

Python < 2.7.9 does not verify SSL certificates, so it's just OK.

Possibly a duplicate of #7309. Could you check whether there are expired certificates in Windows Certificate Store? See https://github.com/rg3/youtube-dl/issues/7309#issuecomment-172354527 for detailed steps. DailyMotion uses certificates from DigiCert company:

Having the same issue here running on Linux with ca-certificates installed.

Workaround include changing config, see https://access.redhat.com/articles/2039753.

The real fix for me was setting environment variable: SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt

I'd suggest to use "requests" instead if possible, see https://github.com/lepture/flask-oauthlib/issues/200

You may also use my Dockerized youtube-dl: wernight/youtube-dl.
