Issue with AWS ECS and Load Balancer Setup – 403 Forbidden Error During Deployment

I'm implementing infrastructure on AWS using ECS with Docker and a Load Balancer. As part of the process, I'm using AdminAuth for authentication. However, when I click the **"Implement" button to proceed with the deployment, I encounter a 403 Forbidden" error.

What could be causing this issue, and what steps should I take to resolve it?
