You will need to make sure your bot process is able to bind to a service port and communicate how that port can be reached from the public internet. If you've got any Firewalls / NAT's in the way, they need to be configured to pass traffic towards the process your bot runs on.

That's why either you need ngrok pro, or you need to expose your host to the internet with port fowardings / NAT rules.
