Docker swarm with Nginx as Reverse Proxy

General
1

Hi Team,

There are two web applications that were running fine on our server, but after i moved this into docker swarm along with nginx configuration there is an issue , the web page is not loading. im sure its because of nginx. but this web applications are running fine without docker with same nginx configuration. I need to move this docker swarm to production within one or two days, but im stuck .

docker stack file for admin

networks:
    dev_shared_admin: 
        external: true

services:
    admintc:
        image: salmanshariff171/devadmin:V1.0.0.2
        deploy:
            replicas: 2
            update_config:
                parallelism: 1
                delay: 10s
                failure_action: rollback
            restart_policy:
                condition: on-failure
                max_attempts: 3
                delay: 20s
                window: 120s
        networks:
            - dev_shared_admin
        ports:
            - target: 5173
              published: 5173
              protocol: tcp
              mode: ingress

    proxy_server:
        image: nginx
        ports:
            - 8080:80
        volumes:
            - /root/dockers_configuration/admin_nginx.conf:/etc/nginx/nginx.conf  # Main Nginx config
            - /root/dockers_configuration/admin_nginx-entrypoint.sh:/usr/local/bin/nginx-entrypoint.sh
        networks:
            - dev_shared_admin
        depends_on:
            - admintc
        entrypoint: ["/usr/local/bin/nginx-entrypoint.sh"]  # Use the custom entrypoint script

This are the complete containers for docker stack devadmin
