ssl ,urllib3,requests .exceptions.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:548)

Question

I'm developing an application that collects information from YouTube via the YouTube APIv3. I'm using yapi package from github. I was working in Python2.7 and it worked fine.

But when I upgraded to Python 3.3 it suddenly gave me a certificate error.

Input

import yapi
Youtube = yapi.YoutubeAPI('API KEY')
Results = Youtube.general_search('keyword', max_results=10)
print(Results)

Output

Process finished with exit code 1

I had to change to Python 3.4 to try support other functions that I was using that only supported 3 and up.

Answer 1

Try and change the manager.py line 47 from

con = requests.get(req_url)

to

 con = requests.get(req_url, verify=False)

There could be an issue with the SSL certificate.

Could be related to an issue I was having, using the requests library.
