deployed concourse-lite on aws but unable to login into console

[ghost]

Hi, we deployed concourse on aws in public subnet with following network configuration:
bosh2 create-env concoursetest.yml -o ./infrastructures/aws.yml -l ../versions.yml -l propertiestest.yml --vars-store creds.yml --state state.json -v internal_cidr=10.4.0.0/24 -v internal_gw=10.4.0.1 -v internal_ip=10.4.0.112 -v public_ip=10.4.0.112
under infrastructure/aws.yml I added auto assign public ip property

public ip I am getting 18.237.141.40
so the concourse lite console is available on this URL " http://18.237.141.40:8080/ " but I am unable to login, while login it redirecting to http://10.4.0.112:8080/ which is external URL,

on cli side, I am able to login with the command " fly2 -t concourse-lite login -c http://18.237.49.103:8080 --username concourse --password absbqwbdu "
so please suggest how to configure aws for concourse lite so I can access through the console.
are we using the right configuration?
