Description

rtm_connect() is always returning False

Reproducible in:

following guide here will show the issue:
http://slackapi.github.io/python-slackclient/real_time_messaging.html#connecting-to-the-real-time-messaging-api

For my project I was using docker with python 2.75 + ubuntu 16.04

Steps to reproduce:

1. Follow guide the line sc.rtm_connect() will always return False

• This was working up to a week ago. I rebuilt containers with slack project and they all started seeing this. Nothing else was change in container except moving them to a different instance. Retried on the old instance to verify it wasn't network and problem was also seen then.

Expected result:

sc.rtm_connect() should return true

Actual result:

Always returns false.

Extra Info:

I got feedback from slack about the issue and they were suggesting that I try out the newer rtm.connect method
