Running docker stack deploy not able to connect to app. Docker-compose works fine

I am trying to get a very simple docker-swarm going. If I start the container using docker-compose up -d I am able to go to locahost and see the 'Hello message'. Running docker stack deploy -c docker-compose.yml swar starts the swarm fine. docker ps

docker service ls

However navigating to localhost, 0.0.0.0, 127.0.0.1 or IP of machine doesn't work, it just timesout with 'This site can't be reached. took too long to respond.' Ive also tried it with another small tutorial from github, which also has same issue. Any ideas what is wrong?

server.js:

const express = require("express");
const os = require("os");

const app = express();

app.get("/", (req, res) => {
  res.send("Hello from Swarm " + os.hostname());
});

app.listen(3000, () => {
  console.log("Server is running on port 3000");
});

docker-compose.yml:

version: "3"

services:
  web:
    build: .
    image: takacsmark/swarm-example:1.0
    ports:
      - 80:3000
    networks:
      - mynet

networks:
  mynet:

Dockerfile:

FROM node:11.1.0-alpine

WORKDIR /home/node

COPY . .

RUN npm install

CMD npm start

EDIT: running wget < my computer ip > just hangs.

--2021-05-28 16:59:52--  http://<ip>/
Connecting to <ip>:80... 

curl < ip > just hangs no output.

Ive initialised the swarm included advertise ip aswell

docker swarm init --advertise-addr <my address> 

And still no luck.

My docker version is 20.10.5, docker-compose version: 1.25.0

For anyone ever getting this sort of problem. Problem was the version of docker. Ive removed 20.10.15 and reinstalled a docker 19.03.10. To install custom docker instead of latest follow steps. https://docs.docker.com/engine/install/ubuntu/ locahost doesnt work, but run hostname -I to get the ip of your machine and paste that in. Will work then.
