Not opening GUI after deploying stack in Virtual Machine

[tahmidul99]

Hi,
I installed docker in Oracle VM. Operating System "Debian Buster". I'm using Portainer.io for docker GUI.
In the Portainer, I successfully deployed a stack of FreePBX with this docker compose yml code:

version: '2'

services:
  freepbx-app:
    container_name: freepbx-app
    image: tiredofit/freepbx
    ports:
     #### If you aren't using a reverse proxy
      - 2000:80
     #### If you want SSL Support and not using a reverse proxy
     #- 443:443
      - 5060:5060/udp
      - 5160:5160/udp
      - 18000-18100:18000-18100/udp
     #### Flash Operator Panel
      - 4445:4445
    volumes:
      - ./certs:/certs
      - ./data:/data
      - ./logs:/var/log
      - ./data/www:/var/www/html
     ### Only Enable this option below if you set DB_EMBEDDED=TRUE
     #- ./db:/var/lib/mysql
     ### You can drop custom files overtop of the image if you have made modifications to modules/css/whatever - Use with care
     #- ./assets/custom:/assets/custom

    environment: 
      - VIRTUAL_HOST=hostname.example.com
      - VIRTUAL_NETWORK=host
     ### If you want to connect to the SSL Enabled Container 
     #- VIRTUAL_PORT=443
     #- VIRTUAL_PROTO=https
      - VIRTUAL_PORT=80
      - LETSENCRYPT_HOST=hostname.example.com
      - [email protected]

      - ZABBIX_HOSTNAME=freepbx-app

      - RTP_START=18000
      - RTP_FINISH=18100
    
     ## Use for External MySQL Server
      - DB_EMBEDDED=FALSE

     ### These are only necessary if DB_EMBEDDED=FALSE
      - DB_HOST=freepbx-db
      - DB_PORT=3306
      - DB_NAME=asterisk
      - DB_USER=asterisk
      - DB_PASS=asteriskpass
    
     ### If you are using TLS Support for Apache to listen on 443 in the container drop them in /certs and set these:
     #- TLS_CERT=cert.pem
     #- TLS_KEY=key.pem
     
    restart: always
    networks:
      - proxy-tier

    ### These final lines are for Fail2ban. If you don't want, comment and also add ENABLE_FAIL2BAN=FALSE to your environment
    cap_add:
      - NET_ADMIN
    privileged: true

  freepbx-db:
    container_name: freepbx-db
    image: tiredofit/mariadb
    restart: always
    volumes:
      - ./db:/var/lib/mysql
    environment:
      - MYSQL_ROOT_PASSWORD=password
      - MYSQL_DATABASE=asterisk
      - MYSQL_USER=asterisk
      - MYSQL_PASSWORD=asteriskpass
    networks:
      - proxy-tier

  freepbx-db-backup:
    container_name: freepbx-db-backup
    image: tiredofit/db-backup
    links:
     - freepbx-db
    volumes:
      - ./dbbackup:/backup
    environment:
      - ZABBIX_HOSTNAME=freepbx-db-backup
      - DB_HOST=freepbx-db
      - DB_TYPE=mariadb
      - DB_NAME=asterisk
      - DB_USER=asterisk
      - DB_PASS=asteriskpass
      - DB_DUMP_FREQ=1440
      - DB_DUMP_BEGIN=0000
      - DB_CLEANUP_TIME=8640
      - COMPRESSION=BZ
      - MD5=TRUE
    networks:
      - proxy-tier
    restart: always

networks:
  proxy-tier:
      driver: bridge

After deploying the stack the starting admin page isn't coming. But in the containers section, it's showing "Running" status!
Login address I'm trying: http://1.1.1.11:2000

I'm not sure what I did wrong! I'm new in docker but experienced in FreePBX. I've got a PBX server up and running in Raspberry Pi4 right now.

Can anyone help me with this issue, please? It'll be a great help for me!

@tahmidul99 did you find a solution, I have a similar yaml, also with bridged network and commented out the proxy stuff (virtual, letsencryp). but cannot connect http to local rasPi.
