Make sure you have
pip install certifi
Installs Mozilla CA-bundle, apparently it's not included with Python3 installations. But it fixed a similar issue for me.

@dezza Nope. It's not working but thanks for help. Issue is still active

[jaimet]

Does this help? (I just had a similar problem, and the info in that link "fixed" it for me).
