React history.push() not rendering new component

Question

I have a React.js project with a simple sign in function. After the user is authorized, I call history.push method which changes the link in the address bar but does not render the new component. (I use BrowserRouter)

My index.js component:

ReactDOM.render(
  <Provider store={createStore(mainReducer, applyMiddleware(thunk))}>
    <BrowserRouter>
      <Main />
    </BrowserRouter>
  </Provider>,
  document.getElementById('root')
);

My Main.js component:

const Main = (props) => {
  return (
    <Switch>
      <Route exact path="/" component={Signin} />
      <Route exact path="/servers" component={Servers} />
    </Switch>
)}

export default withRouter(Main);

My Action Creator:

export const authorization = (username, password) => (dispatch) =>
  new Promise ((resolve, reject) => {
    fetch(url, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        username: username,
        password: password,
      })
    }).then( response => {
      if (response.ok) {
          response.json().then( result => {
            console.log("API reached.");
            dispatch(logUserIn(result.token));
            resolve(result);
        })
      } else {
        let error = new Error(response.statusText)
        error.response = response
        dispatch(showError(error.response.statusText), () => {throw error})
        reject(error);
      }
    });
  });

My Signin.js component:

 handleSubmit(event) {

    event.preventDefault();

    this.setState({ isLoading: true })

    const { username, password } = this.state;
    this.props.onLoginRequest(username, password, this.props.history).then(result => {
      console.log("Success. Token: "+result.token); //I do get "success" in console
      this.props.history.push('/servers') //Changes address, does not render /servers component
    });

  }

const mapActionsToProps = {
  onLoginRequest: authorization
}

The weirdest thing is that if I change my handleSubmit() method to this - everything works perfectly:

  handleSubmit(event) {

    event.preventDefault();

    this.setState({ isLoading: true })

    const { username, password } = this.state;
    this.props.onLoginRequest(username, password, this.props.history).then(result => {
      console.log("Success. Token: "+result.token);
      //this.props.history.push('/servers')
    });
    this.props.history.push('/servers')
  }

The same issue comes if I try to push history from the componentWillReceiveProps(newProps) method - it changes address but does not render new component. Could someone please explain why this happens and how to fix it?

You need to apply withRouter to use this.props.history.push('/page') in every component that use "push"

import { withRouter } from 'react-router-dom';
.....
export default
        withRouter(MoneyExchange);

this is important when using push.
