Answer 1

Make it sure that your component is imported in app.module.ts. In my case that it was the reason where I forgot to include the component in the declaration

@NgModule({
  declarations: [
    AppComponent,
    HomeComponent,
    IndexComponent
  ],
  imports: [
    BrowserModule, FormsModule, HttpClientModule, RouterModule.forRoot(routes)
  ],
  exports: [RouterModule],
  providers: [],
  bootstrap: [AppComponent]
})

Also make sure you restart server when new modules and components are added while ng serve it is also a reaosn when this problem occur. So, the basic solution is to quit the server and ng serve again.
