HAProxy + Wordpress into Docker : DOWN status

Hello,

I have a server with HAProxy & Docker, I have installed Wordpress on it, but it seems HAProxy cannot connect to Wordpress. On the server I have a certificate and Wordpress seems running.

I noticed that on the “stats” the Wordpress status is DOWN !
(I have other ‘backend’ between HAProxy & Docker that work… but this one :-P)

So, how can I debug and/or fix this problem, if someone has an idea please?

Here is the HAProxy config :

frontend https-in
    bind *:80
    bind *:443 ssl crt  /usr/local/etc/haproxy/certs/socloze.com.pem
    #http-request add-header X-Forwarded-Proto https
    http-request redirect prefix https://www.%[hdr(host)] code 301 if { hdr(host) -i socloze.com }
    http-request redirect prefix https://%[hdr(host)] code 301 if { hdr(host) -i www.socloze.com } !{ ssl_fc }
    
    acl acl_blog hdr(host) -i blog.socloze.com
    
    use_backend be-blog if acl_blog
    
    backend be-blog
    option  forwardfor
    http-request add-header X-Forwarded-Proto https
    redirect scheme https code 301 if !{ ssl_fc }
    server wordpress wordpress:1200 check ssl none resolvers docker init-addr libc,none

And the docker compose file too

version: '3.3'
services:
  db:
    image: mysql:5.7
    environment:
      MYSQL_DATABASE: wordpress
      MYSQL_PASSWORD: Mypassword#
      MYSQL_ROOT_PASSWORD: Mypassword#
      MYSQL_USER: wordpress
    volumes:
     - db_data:/var/lib/mysql
    networks:
     - default
    logging:
      driver: json-file
  wordpress:
    image: wordpress:latest
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_PASSWORD: Mypassword#
      WORDPRESS_DB_USER: wordpress
    ports:
     - 1200:80
    volumes:
     - wordpress_files:/var/www/html
    networks:
     - haproxy-net
     - default
    logging:
      driver: json-file
networks:
  default:
    driver: overlay
  haproxy-net:
    external: true
volumes:
  db_data:
    driver: local
    driver_opts:
      device: /data/mysql
      o: bind
      type: none
  wordpress_files:
    driver: local
    driver_opts:
      device: /data/wordpress
      o: bind
      type: none

BTW, I have switched to this, but it does not solve anything

server wordpress wordpress:1200 check resolvers docker init-addr libc,none
