Unable to forward nginx in a docker container to localhost 3000

I'm currently trying to configured nginx within a docker container to redirect to localhost:3000 when I navigate to localhost:8080. From reading the documentation it seems I need to map the ports to redirect requests to port 80 in the container. However, when I build an image based on the following Dockerfile:

FROM alpine

RUN apk --no-cache add nginx

COPY ./nginx.conf /etc/nginx/nginx.conf

RUN mkdir -p /run/nginx

EXPOSE 80 443

CMD ["nginx", "-g", "daemon off;"]

and run the container mapping the port 8080 to port 80 with the following command:

docker run -p 8080:80  nginx-server

When I navigate to localhost:8080 I'm not being redirected to localhost:3000 and I get

localhost didn’t send any data.

After doing some digging it seems I need to change my nginx configuration to point to proxy_pass http://host.docker.internal.However, this did not work and when I make a request to localhost:8080 I get nothing. here is my nginx configuration:

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  65;

    server {
        listen       127.0.0.1;
        server_name  localhost;

        location / {
            proxy_pass http://host.docker.internal:3000;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    }

    include servers/*;
}

Any idea what am I doing wrong?
