I am trying to implement public, private and unprotected routes in react app (webpack based). We have defined routes where we have added public, private and unprotected routes. The app is loading '/login' by default, but

Whenever we are reloading http://localhost:3000/login or any component like http://localhost:3000/dashboard etc, we are getting error

Cannot GET /login

Can someone please suggest some solution?

app.js

const App = () => {
  return (
    <AuthProvider>
    <BrowserRouter>
      <Suspense fallback={<div>Loading...</div>}>
        <Routes>
          <Route path="/" element={<Navigate to="/login" replace />} />
          <Route element={<PublicRoute />}>
            <Route path="/login" element={<Login />} />
            <Route path="/signup" element={<Signup />} />
          </Route>
          <Route element={<PrivateRoute />}>
            <Route path="/dashboard" element={<Dashboard />} />
          </Route>
          <Route path="/home" element={<Home />} />
        </Routes>
      </Suspense>
    </BrowserRouter>
  </AuthProvider>
  )
};

export default App

AuthContext.js

import React, { createContext, useContext, useState, useEffect } from "react";

const AuthContext = createContext();

export const useAuth = () => useContext(AuthContext);

export const AuthProvider = ({ children }) => {
    const [user, setUser] = useState(() => {
        const savedUser = localStorage.getItem("user");
        return savedUser ? JSON.parse(savedUser) : null;
    });

    useEffect(() => {
        const savedUser = localStorage.getItem("user");
        if (savedUser) setUser(JSON.parse(savedUser));
    }, []);

    const login = (userData) => {
        setUser(userData);
        localStorage.setItem("user", JSON.stringify(userData));
    };

    const logout = () => {
        setUser(null);
        localStorage.removeItem("user");
    };

    return (
        <AuthContext.Provider value={{ user, login, logout }}>
            {children}
        </AuthContext.Provider>
    );
};

publicRoute.js

import React from "react";
import { Navigate, Outlet } from "react-router-dom";
import { useAuth } from "../context/AuthContext";

const PublicRoute = () => {
    const { user } = useAuth();
    return !user ? <Outlet /> : <Navigate to="/dashboard" />;
};

export default PublicRoute;

PrivateRoute.js

import React from "react";
import { Navigate, Outlet } from "react-router-dom";
import { useAuth } from "../context/AuthContext";

const PrivateRoute = () => {
    const { user } = useAuth();
    return user ? <Outlet /> : <Navigate to="/login" />;
};

export default PrivateRoute;

webpack.config.js

const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");

const webpack = require("webpack");

// Load environment variables from .env
dotenv.config();

module.exports = {
