Description

When running the following script

# heartbeat.py
import asyncio
from copra.websocket import Channel, Client

KEY = '<mykey>'
SECRET = '<mysecret>''
PASSPHRASE = '<mypassphrase>'

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    ws = Client(loop, Channel('heartbeat', 'BTC-USD'))
    try:
        loop.run_forever()
    except KeyboardInterrupt:
        loop.run_until_complete(ws.close())
        loop.close()

I get the following exception related to ssl verification

Additional information

When I run this on a docker image https://github.com/docker-library/python/blob/878ffe36c2391279e673a44a011f5c65943b5eb8/3.6/jessie/Dockerfile

It runs without issue so I think it's a macos issue

Based on your configuration, your problem sounds a lot like Rapptz/discord.py#423 (comment). Can you verify that you have the certificate installed?
