i use default setting in docker-compose.yml and last version of docker 26 It seems that the web server is not active

  front:
    image: ${DOCKER_ORG:-ghcr.io/mailu}/${DOCKER_PREFIX:-}nginx:${MAILU_VERSION:-2.0}
    restart: always
    env_file: mailu.env
    logging:
      driver: journald
      options:
        tag: mailu-front
    ports:
      - "127.0.0.1:80:80"
      - "127.0.0.1:443:443"
      - "127.0.0.1:25:25"
      - "127.0.0.1:465:465"
      - "127.0.0.1:587:587"
      - "127.0.0.1:110:110"
      - "127.0.0.1:995:995"
      - "127.0.0.1:143:143"
      - "127.0.0.1:993:993"
    networks:
      - default
      - webmail
      - radicale
    volumes:
      - "/mailu/certs:/certs"
      - "/mailu/overrides/nginx:/overrides:ro"
    depends_on:
      - resolver
    dns:
      - 192.168.203.254

also mailu.env

SECRET_KEY=3Mss4DI0U3CZY7Y7

# Subnet of the docker network. This should not conflict with any networks to which your system is connected. (>
SUBNET=192.168.203.0/24

# Main mail domain
DOMAIN=my.domainb.com

# Hostnames for this server, separated with comas
HOSTNAMES=mail.domainb.com

# Postmaster local part (will append the main mail domain)
POSTMASTER=admin

# Choose how secure connections will behave (value: letsencrypt, cert, notls, mail, mail-letsencrypt)
TLS_FLAVOR=cert

# Header to take the real ip from
REAL_IP_HEADER=

# IPs for nginx set_real_ip_from (CIDR list separated by commas)
REAL_IP_FROM=

......

so DNS have a record for my.domainb.com and mail.domainb.com .

return docker log front
