React Router not rendering component initially - reactjs

Question

This is weird one for me. I start my app up locally. I just have a Header and TaskPage in my App like so.
import React, { Component } from 'react';
import { withRouter } from 'react-router-dom';
import { connect } from 'react-redux';
import Header from '../components/header';
import TasksPage from '../pages/tasks';
import { Route } from 'react-router';
class App extends Component {
render() {
return (
<div>
<Header />
<main>
<Route exact path="/" component={TasksPage} />
</main>
</div>
);
}
}
export default withRouter(connect()(App));
And then my router stuff.
import './views/styles/styles.css';
import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { ConnectedRouter } from 'react-router-redux';
import history from './history';
import configureStore from './store';
import registerServiceWorker from './utils/register-service-worker';
import App from './views/app';
import TaskPage from './views/pages/tasks'
const store = configureStore();
const rootElement = document.getElementById('root');
function render(Component) {
console.log('COMPONENT::',Component);
ReactDOM.render(
<Provider store={store}>
<ConnectedRouter history={history}>
<div>
<Component />
</div>
</ConnectedRouter>
</Provider>,
rootElement
);
}
if (module.hot) {
module.hot.accept('./views/app', () => {
render(require('./views/app').default);
})
}
registerServiceWorker();
I initially get a blank page. But if I make a change to the App page and save it while the app is running, like just a space or line return, something insignificant, I get my tasks page suddenly. It works fine then. I have no errors in my console at any point during this process so I think I have something wrong with my routing somewhere when the app initially loads.
Or maybe it has something to do with this TaskPage.

}
componentWillReceiveProps(nextProps) {
if (nextProps.location.search !== this.props.location.search) {
this.props.filterTasks(
this.getFilterParam(nextProps.location.search)
);
}
}
componentWillUnmount() {
// this.props.unloadTasks();
}
getFilterParam(search) {
const params = new URLSearchParams(search);
return params.get('filter');
}
render() {
return (
<div className="g-row">
<div className="g-col">
<TaskForm handleSubmit={this.props.createTask} />
</div>
<div className="g-col">
<TaskFilters filter={this.props.filterType} />
<TaskList
removeTask={this.props.removeTask}
tasks={this.props.tasks}
updateTask={this.props.updateTask}
/>
</div>
</div>
);
}
}

const mapStateToProps = createSelector(
getTaskFilter,

(filterType, tasks) => ({
filterType,
tasks
})

const mapDispatchToProps = Object.assign(

tasksActions
);
export default withRouter(connect(
mapStateToProps,
mapDispatchToProps
)(TasksPage));

So something with the hotloading or maybe the way I had it setup?? Im not saying its the best answer but it did resolve my problem. If someone can explain this better than I'll happily accept a clearer response on the subject
This should have worked based on the docs. But I commented it out and went back to just using ReactDOM.Render with my . No wrapped Function or . And oddly hotloading still seems to work.
// function render(Component) {
ReactDOM.render(
<Provider store={store}>
<ConnectedRouter history={history}>
<div>
<App/>
</div>
</ConnectedRouter>
</Provider>,
rootElement
);
// }
// if (module.hot) {
// module.hot.accept('./views/app', () => {
// render(require('./views/app').default);
// })
// }
FYI - Im react-router 4.x, Redux 5.x, React 15.x.
