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 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.
