Can't access to docker itzg/minecraft-server on dedicated server

Question

I am trying to host a Minecraft server in a docker container on a dedicated server (Ubuntu 20.04). I am using the itzg/minecraft-server image with docker-compose to create my container.
I have no errors when creating the container nor when launching the minecraft server in the container logs. BUT when I connect to the server with the public ip of my vps and port 25565, I have

Can't connect to server: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection timed out: no further information:

I also tried to start the server as idzg suggests, following this instructions :

To simply use the latest stable version, run

docker run -d -p 25565:25565 --name mc itzg/minecraft-server

where the standard server port, 25565, will be exposed on your host machine.

but the problem is the same

The container is OK

CONTAINER ID   IMAGE                   COMMAND    CREATED          STATUS                    PORTS                                                      NAMES

docker-compose.yml

version: "3.7"

services:
  mc:
    container_name: mc
    image: itzg/minecraft-server
    ports:
      - 25565:25565
    environment:
      EULA: "TRUE"
    volumes:
      # attach a directory relative to the directory containing this compose file
      - /home/neuromob/minecraft-server/data_tmp:/data

Additionally, I have a second container with a nginx and node web server to build a vue.js project. This container is still down when I tried to start my Minecraft server, but I prefer to specify it if ever it can conflict for the connection ... ? But I don't think so.

For people who have the same problem, I solved it by simply opening port 25565 on the VPS host site
