Hi, First of all, Thanks for this awesome repository. I have recently installed the repo to my macbook. But I'm having trouble.

I had installed all python packeges. And I run npm start. after that I visited http://localhost:2018/ I clicked 3 times to connect and I get this error. The output in console:

npm start

> npm run dev

> whatsapp-web-reveng@1.0.0 dev /Users/user/codeforlaravel/app/whatsapp-web-reveng

@sigalor Please help me

Hi, so several other people had this issue already (e.g. #60), but as I am not able to reproduce the [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:726) error and none of them did sufficient debugging of not only their Python installation but also their system configuration, I just cannot help them.

Trying a shot in the dark here, you could reinstall Python 2, try using the simple-websocket-server library to connect to another WebSocket via SSL (i.e. wss://...) or check your local store of trusted certificates and whether Python is able to access them.
