I finally fixed it using the devServer.public configuration option.

Below is my vue.config.js file:

module.exports = {
    devServer: {
        disableHostCheck: true,
        port: 4000,
        public: '0.0.0.0:4000'
    },
    publicPath: "/"
}

I got my answer from reading this.

// NOTE: if 0.0.0.0 : 4000(port #) does not work, use localhost:4000 instead
