SSL error - certificate verify failed - AWS IOT (basicPubSub.py)

Question

I am trying to use the AWS IoT basicPubSub.py script to test my AWS connection, but I keep getting this error. I have tried various fixes, but cannot resolve the problem.

I have tried it using my MacBook and RPi and still have the same issue.
