Communicating to Pi4 HomeAssistant

I am unable to communicate with (Onboarding Home Assistant) on my Raspberry Pi 4. I have loaded the Home Assistant OS - It works fine but all I get is a line by line HomeAssistant screen command facility on my Pi. Communicating via a Homeassistant.local:8123 gets me nowhere. - Help!!!

try the pi’s IP adress, like http://123.123.123.12:8123
