Open a terminal and take a look at    Applications Python 3 6 Install Certificates command   Python 3 6 on MacOS uses an embedded version of OpenSSL  which does not use the system certificate store  More details here    To be explicit  MacOS users can probably resolve by opening Finder and double clicking Install Certificates command
