HA in docker in raspian

Hello,
I installed home assistant in a docker on my pi4 8gb, on pi os/raspian. This tutorial i used;

When i installed it, and i want to get into HA, it says connection refushed. what do i have to do, to fix it?

That guide does not show docker install.

LAN may not be ETH0

Try “ifconfig” to see network

HA probably not running. Try “ps” to show running process and verify it running

Thanks for the reply
Lan is my eth0
in ps i see docker running, in docker i see hassio supervisor
