Приложение slackclient не работает после сборки PyInstaller, но отлично работает из командной строки python

Я тестирую слабый API, используя slackclient, используя следующий код Python:

# pip install slackclient to install SlackClient library
from slackclient import SlackClient
import json
import time


def test_slack(sc):
    # use for debugging
    print("Testing API")
    print(80 * "=")
    print (sc.api_call("api.test"))


def get_channel_info(sc, channel):
    # get info about the channel
    print("Getting Channel Info")
    print(80 * "=")
    print (sc.api_call("channels.info", channel=channel))


def get_list_of_channels(sc):
    print("Getting List of Channels")
    print(80 * "=")
    # get list of channels
    channels = sc.api_call("channels.list")
    channels = json.dumps(channels)
    channels = json.loads(str(channels))
    print channels
    return channels


def display_channels(channels):
    print("Display Channels")
    print(80 * "=")
    for i in channels['channels']:
        print("Channel:", i['name'], i['id'])


def post_message(sc, text, channel, icon_url, username):
    print("Posting Message to Slack")
    print(80 * "=")
    # post a message into the #general channel
    print (sc.api_call("chat.postMessage", channel=channel, text=text, username=username, icon_url=icon_url,
                       unfurl_links="true"))


def get_users(sc):
    print("Get Users")
    print(80 * "=")
    # call the users.list api call and get list of users
    users = (sc.api_call("users.list"))
    print users
    users = json.dumps(users)
    users = json.loads(str(users))
    return users


def display_users(sc, users):
    print("User List")
    print(80 * "=")
    # display active users
    for i in users['members']:
        print users
        # don't display slackbot
        if i['profile']['real_name'] != "slackbot":
            # don't display deleted users
            if not i['deleted']:
                # display real name
                print (i['profile']['real_name'])


def main():
    # define variables
    token = "HERE YOUR SLACK TESTER TOKEN"
    channel = "general"
    username = "moderator"
    icon_url = ""
    # connect to Slack
    sc = SlackClient(token)
    # test slack
    test_slack(sc)
    # get channel info
    get_channel_info(sc, channel)
    # get list of channels
    channels = get_list_of_channels(sc)
    # display channels
    display_channels(channels)
    # post message
    post_message(sc, "Testing 123 testing 123.", channel, icon_url, username)
    # get users
    users = get_users(sc)
    # display users
    display_users(sc, users)

    if sc.rtm_connect():
        while True:
            for slack_message in sc.rtm_read():
                print slack_message
                message = slack_message.get("text")
                user = slack_message.get("user")
                if not message or not user:
                    continue
                print "User: ", user, message
            time.sleep(3)
    else:
        print "Connection Failed, invalid token?"

main()

Это отлично работает из среды PyCharm или из командной строки python. После создания исполняемого файла Windows с помощью PyInstaller приложение больше не может подключаться, поскольку rtm_connect() всегда возвращает False. Токен или что-то еще не было изменено.

Любые предложения о том, как отладить это или любые идеи, которые могут вызвать проблему с подключением?
