Error when start in python

[jfleclerc]

Hi guys I'm a beginner in programming and Python, I get this error when starting ravpy:
requests.exceptions.ConnectionError: HTTPConnectionPool(host='0.0.0.0', port=9999): Max retries exceeded with url: /client/ftp_credentials/ (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f44d3c92400>: Failed to establish a new connection: [Errno 111] Connection refused'))

** my code is this:

#!/usr/bin/env python3

from dotenv import load_dotenv
from pathlib import Path

dotenv_path = Path('/home/jf/.env')
load_dotenv(dotenv_path=dotenv_path)

from ravpy.initialize import initialize
initialize(ravenverse_token='xxxxxxxxx')

from ravpy.distributed.participate import participate
participate()

** my env file is this:

RAVENVERSE_URL=http://0.0.0.0:9999
RAVENVERSE_FTP_URL=0.0.0.0

Is it because of the ravenverse url? should i change something ?
Thanks a lot and thanks for that amazing programming of yours too!
