Deploy single page application Angular: 404 Not Found nginx

I Have an Angular application. I run the command ng build --prod --aot to generate the dist folder. In the dist folder I created a file named Staticfile then I uploaded the dist folder to pivotal.io with the following commands:

1. cf push name-app --no-start
2. cf start name-app

The app runs well. I have a nav bar, so when I change the path with navbar everything works fine. But when I do it manually (I enter the url myself) I have this error 404 Not Found nginx. This my app.component.ts:

const appRoutes: Routes = [
  { path: 'time-picker', component: TimePickerComponent },
  { path: 'material-picker', component: MaterialPickerComponent },
  { path: 'about', component: AboutComponent },
  { path: 'login', component: LoginComponent },
  { path: 'registration', component: RegistrationComponent },
  {
    path: '',
    redirectTo: '/time-picker',
    pathMatch: 'full'
  }
];

@NgModule({
  declarations: [
    AppComponent,
    TimePickerComponent,
    MaterialPickerComponent,
    DurationCardComponent,
    AboutComponent,
    LoginComponent,
    RegistrationComponent,
  ],
  imports: [RouterModule.forRoot(
    appRoutes
    // ,{ enableTracing: true } // <-- debugging purposes only
  ),
    FormsModule,
    BrowserAnimationsModule,
    BrowserModule,
    MdCardModule, MdDatepickerModule, MdNativeDateModule, MdInputModule

  ],
  providers: [{ provide: DateAdapter, useClass: CustomDateAdapter }],
  bootstrap: [AppComponent]
})
export class AppModule {
  constructor(private dateAdapter: DateAdapter<Date>) {
    this.dateAdapter.setLocale('fr-br');
  }
}
