Project description:
"My simple chat app is built with a React frontend and Golang backend and served by Nginx on an Ubuntu EC2 instance (public IP). When the browser tries to POST to API/* I receive the error:

“Access to fetch at 'http://localhost:8080/register' from origin 'http://public-ip' has been blocked by CORS policy: The request client is not a secure context and the resource is in more-private address space `loopback`.”

I need the CORS policy tightened to allow requests only from specific public IPs (not a blanket *). Whether the change belongs in the Go server, the Nginx reverse-proxy rules, or both. Need more support to end the final deployment into ec2 and aws rds connection." (client-provided description)
