ORDS - Bad gateway

Hi Experts,

we have installed ORDS(23.4) in server in private subnet and currently accessible with ipadress with http://172.******:8080/ords
We have created OCI load balancer in public subnet without ssl. We got the public IP.
When we hit the public ip,http://public ip → it should take me to landing page, but it throws bad gateway error.
Do we need to make any changes to settings.xml. Once this test is successful,then we will add DNS entry to this public ip.
[ordsuser@srv-dev-001 global]$ cat settings.xml
