SSL: CERTIFICATE_VERIFY_FAILED

[photogadam]

I've tried the examples in the how to along with ticker.updates.py and the only response I'm receiving is ssl.SSLError. Any suggestions? Thanks in advance.

Thanks for the reply. I tried your instructions from https://github.com/slazarov/python-bittrex-websocket/issues/73#issuecomment-417256152 (using python3 and instead of python and installed bittrex_websocket through pip3) and this is what I recieved:

Just an update, I was able to install this to my raspberry pi and it is working, so I'm not sure what is wrong on my end. Any advice would be helpful.

Just another update. I reinstalled everything and am still getting the error. I ran across this, but am not sure if it is relevant (I am on osx): https://github.com/slackapi/python-slackclient/issues/334

Hi, do you get the same error if you run it in a docker instance?

I'm not familiar with docker. But I'll try to look into and give it a try for you in the next few days.

Docker isn't working in the OSX Mojave update... I have this working in linux and I'll just use it there instead.
