How to access the Kong Portal - When it has been Install using Terraform

As i have successfully installed the Kong Terraform Enterprise module on AWS.Now how to access the Kong Portal. when i am accessing it with load balancer DNS then in browser i am getting this error " 502 Bad Gateway".

For Example when we have install kong on Ubuntu we can access the kong portal using like this http://12.13.14.0:8002 and user will be able to access the kong Developer portal and dashboard.

so in a similar way when we have install the kong using terraform , so on which port or IP or DNS shall we access the Kong Dashboard or Kong Portal.
