Could you visit https://www.dailymotion.com/ in Internet Explorer and try again?

[RingoTheDog]

Same Result after opening in IE (with python 3.5.1)...BUT I discovered it does work correctly with Python 2.7.5

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

[yan12125]

Possibly a duplicate of #7309. Could you check whether there are expired certificates in Windows Certificate Store? See #7309 (comment) for detailed steps. DailyMotion uses certificates from DigiCert company:

 0 s:/C=FR/ST=Ile-de-France/L=Paris/O=Dailymotion SA/CN=*.dailymotion.com
   i:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert SHA2 High Assurance Server CA
 1 s:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert SHA2 High Assurance Server CA
   i:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert High Assurance EV Root CA

[RingoTheDog]

You are on the right track....
I can't find any expired certificates:

...but #7309 mentioned the --no-check-certificate flag...that DOES work (with 3.5.1):

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.
