Getting 127.0.0.1 in request ip header

I have a NestJS server that is deployed on an EC2 instance with nginx. I want to get the client ip address from where request is originating but i get "127.0.0.1" as ip in every request no matter where its coming from.

i have tried getting ip directly from request headers and used @Ip decorator from nestjs as well. but still getting same ip.

i have tried setting headers in nginx config as well like this.

location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                proxy_pass http://127.0.0.1:5001;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header X-Forwarded-Proto $scheme;
        }

In your main.ts's bootstrap method, add this line before app.listen()

app.getHttpAdapter().getInstance().set("trust proxy", true);

This will tell express to trust the proxy IPs and allow you to properly use req.ip or the @Ip() decorator
