docker can’t access container from localhost

I can’t access container app from my host. It is just a simple ExpressJS app I built for testing.
I am running a Windows 10 Pro with Hyper-V.
This is the result of docker version

Below the code and the dockerfile (It works perfectly fine without docker)

// index.js
const app = require('express')();

app.get('/demo', (req, res) => res.json('Demo!'));

const server = app.listen(process.env.PORT, () => {
    console.log(`Listening on ${server.address().address}:${server.address().port}`);
});

// Dockerfile
FROM node:latest

WORKDIR /src

ENV PORT=3001

COPY  ["express-app", "."]

EXPOSE 3001

ENTRYPOINT ["node", "index.js"]

I build the image by docker build -t express -f Dockerfile .

I run the container by docker run express -p 3001:3001

docker ps
4840aa7e327d  express  "node index.js -p 30…"  59 seconds ago  Up 58 seconds  3001/tcp wonderful_easley

docker logs 4840aa7e327d
Listening on :::3001

Inspecting into the container by doing docker inspect 4840... I get
