Python Slackbot not Showing as active and Not responding - python-3.x

Question

The slackbot is not showing as active and not responding. I have used ngrok to set up tunneling from my localhost to allow for the slack bot to be verified. On slack it shows that the request URL has been verified. I have also subscribed to slack events.
I am following, https://medium.com/developer-student-clubs-tiet/how-to-build-your-first-slack-bot-in-2020-with-python-flask-using-the-slack-events-api-4b20ae7b4f86, to get this bot working. Any help would be great. Thanks.

from slackeventsapi import SlackEventAdapter

# This `app` represents your existing Flask app
app = Flask(__name__)
greetings = ["hi", "hello", "hello there", "hey"]
SLACK_SIGNING_SECRET = os.environ['SLACK_SIGNING_SECRET']
slack_token = os.environ['SLACK_BOT_TOKEN']
VERIFICATION_TOKEN = os.environ['VERIFICATION_TOKEN']
#instantiating slack client
slack_client = WebClient(slack_token)
# An example of one of your Flask app's routes
#app.route("/")
def event_hook(request):
json_dict = json.loads(request.body.decode("utf-8"))
if json_dict["token"] != VERIFICATION_TOKEN:
return {"status": 403}
if "type" in json_dict:
if json_dict["type"] == "url_verification":
response_dict = {"challenge": json_dict["challenge"]}
return response_dict
return {"status": 500}

slack_events_adapter = SlackEventAdapter(
SLACK_SIGNING_SECRET, "/slack/events", app

#slack_events_adapter.on("app_mention")
def handle_message(event_data):
def send_reply(value):
event_data = value
message = event_data["event"]
if message.get("subtype") is None:
command = message.get("text")
channel_id = message["channel"]
if any(item in command.lower() for item in greetings):
message = (
"Hello <#%s>! :tada:"
% message["user"] # noqa
)
slack_client.chat_postMessage(channel=channel_id, text=message)
thread = Thread(target=send_reply, kwargs={"value": event_data})
thread.start()
return Response(status=200)
# Start the server on port 3000
if __name__ == "__main__":
app.run(port=3000)

Answer 1

This was the error code that I was running into:
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1091)>.
This brought me to this StackOverflow thread:
Scraping: SSL: CERTIFICATE_VERIFY_FAILED error for http://en.wikipedia.org
Running the certification file in the python folder allowed the slack bot to interact with the channel. The bot is now working but does not show as active.
