Docker can not connect by name to container after restart

I have 2 docker windows container deployed with docker compose. Proxy and Web, Both running Nginx One is reverse proxy other is serving content simple index.html page. When run everything works as expected i can access content via proxy. But if I restart web i get bad gate way and need to restart proxy to get it working again.

How to get this working without need to restart proxy?

Docker-compose

version: '3'

services: 
    web:
        build:
            context: ./web
            dockerfile: ./dockerfile
    proxy:
        build:
            context: ./proxy
            dockerfile: ./dockerfile
        ports:
            - "8089:80"

Proxy: Dockerfile:

FROM sixeyed/nginx:windowsservercore

COPY nginx.conf C:/nginx/conf
CMD C:\nginx\nginx.exe

nginx.config:

events {
}
http {
    server {
        listen       80;
        server_name  localhost;

        location / {
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_pass http://web:80/;
        }
    }
}

web: Dockerfile:

FROM sixeyed/nginx:windowsservercore

COPY nginx.conf C:/nginx/conf
COPY index.html C:/nginx/html/index.html

CMD C:\nginx\nginx.exe

nginx.config:

events {
}

http {
    server {
        listen       80;
        server_name  localhost;

        location / {
            root   html;
            index  index.html index.htm;
        }
    }
}
