access minidla with vlc over zerotier

I have a server with some dockers. One of these is a MiniDLA server. In my local network I can see all movies/songs that minidla server shared, with my smartTV, phone, tablet... Its working.

Now, i added a new docker with zeroTier client in server. I created a network in zerotier Web and I connect server with this. Also I installed zerotier in my phone, and when im using 3g/4g connection, if i connect zerotier vpn, i can see my server. I can use Ssh, ftp, and other services.

But Vlc in phone cannot see the minidla server.

Maybe I lost to configure something?

minidla docker-compose:

version: '3'

services:
  dlna:
    image: vladgh/minidlna
    container_name: minidlna
    restart: unless-stopped
    volumes:
      - ./config/minidlna.conf:/etc/minidlna.conf
      - /media/disk1/series:/media/movies
    network_mode: host
    environment:
      MINIDLNA_MEDIA_DIR_1: /media/movies
      MINIDLNA_FRIENDLY_NAME: HOMESERVER
    deploy:
      resources:
        limits:
          cpus: "1"
          memory: "200M"

minidlna.conf is very simple:

log_dir=/minidlna
db_dir=/minidlna/cache
friendly_name=HOMESERVER
inotify=yes
media_dir=/media/movies

and zerotier docker-compose is also simple too:

services:
  zerotier:
    restart: unless-stopped
    image: zerotier/zerotier
    restart: unless-stopped
    container_name: zerotier
    devices:
      - /dev/net/tun
    network_mode: host
    volumes:
      - ./zerotier-one:/var/lib/zerotier-one/networks.d
    cap_add:
      - NET_ADMIN
      - SYS_ADMIN

I think i forget something, but cannot find it. Can you help me?
