Webpack-dev-server not refreshing page?

Question

JavaScript

There is a webpack build with the following config:

const path = require('path');
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const HtmlWebpackPlugin = require('html-webpack-plugin');
const UglifyJsPlugin = require("uglifyjs-webpack-plugin");
const OptimizeCSSAssetsPlugin = require("optimize-css-assets-webpack-plugin");
const CopyWebpackPlugin = require('copy-webpack-plugin');
const fs = require('fs')

function generateHtmlPlugins(templateDir) {
  const templateFiles = fs.readdirSync(path.resolve(__dirname, templateDir));
  return templateFiles.map(item => {
    const parts = item.split('.');
    const name = parts[0];
    const extension = parts[1];
    return new HtmlWebpackPlugin({
      filename: `${name}.html`,
      template: path.resolve(__dirname, `${templateDir}/${name}.${extension}`),
      inject: false,
    })
  })
}

console.log(path);


const htmlPlugins = generateHtmlPlugins('./src/html/views')

module.exports = {
  mode: "development",
  entry: [
    './src/js/index.js',
    './src/scss/style.scss'
  ],
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: './js/bundle.js'
  },
  optimization: {
    minimizer: [
      new UglifyJsPlugin({
        cache: true,
        parallel: true,
      }),
      new OptimizeCSSAssetsPlugin({})
    ]
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        include: path.resolve(__dirname, 'src/js'),
        use: {
          loader: 'babel-loader',
          options: {
            presets: 'env'
          }
        }
      },
      {
        test: /\.s?css$/,
        use: [{
          loader: MiniCssExtractPlugin.loader
        },
        {
          loader: "css-loader",
          options: {
            sourceMap: true,
            minimize: true,
            url: false
          }
        },
        {
          loader: "sass-loader",
          options: {
            sourceMap: true
          }
        }]
      },
      {
        test: /\.html$/,
        include: path.resolve(__dirname, 'src/html/includes'),
        use: ['raw-loader']
      },
    ]
  },
  devServer: {
    contentBase: path.join(__dirname, 'dist'),
    compress: true,
    hot: true,
    port: 8080
  },
  plugins: [
    new MiniCssExtractPlugin({
      filename: './css/style.css'
    }),
    new CopyWebpackPlugin([{
      from: './src/fonts',
      to: './fonts'
    },
    {
      from: './src/favicon',
      to: './favicon'
    },
    {
      from: './src/img',
      to: './img'
    }
    ])
  ].concat(htmlPlugins)
}

I did layout on this config, everything was fine. I copied this build folder for another project, live reload stopped working in dev-server. What could be the reason?
