I'm working in a project including modern data stack like airflow, airbyte and dbt. My airbyte tool is installed on local and airflow in a docker, I struggle to find the best host to set when adding a new airbyte connection from airflow. Localhost is not right because in this case it concerned the docker itself and when I use the IP address of airbyte this approach doens't satisfy my goal.

I expect a succeeded connection to my airbyte (4.0.0) I have tried the two existing type of connection as Http and Airbyte, I have the right client_id and client_secret but there is error as :
