Python 3.6 can't connect to "server", certificate verification fails.

[mar2n]

Seems like I can't connect to the "server" (or something like that) with python 3.6 getting the error message
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)>

Problem seems to be on the server side where Python does not have the right(?) certificate and can't get access to the server data.

Which operating system are you using?

[mar2n]

OSX 10.12.4

[mar2n]

Quick fixed it by changing the endpoint in pokemontcgsdk/config.py from https to http

This seems to be a common issue on OSX. Maybe try taking a look this some issues like this one? http://stackoverflow.com/questions/42098126/mac-osx-python-ssl-sslerror-ssl-certificate-verify-failed-certificate-verify
