I have an issue regarding a DevNet Learning Lab: CMX 03 Notifications Python; in Cmd I keep coming across the error following the command 'docker-compose up':
"requests.exceptions.ConnectionError: HTTPConnectionPool(host='127.0.0.1', port=4040): Max retries exceeded with url: /api/tunnels (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7fe259c34be0>: Failed to establish a new connection: [Errno 111] Connection refused',))"
Following the directions exactly, with the proper installations made, and environment set up with all the provided files... I don't think it can be a Firewall issue because I replicated the same issue on my computer at home away from work, and it resulted in the same exact issue.
Not quite sure what the solution is, or what I am doing wrong.
