I deployed an app on heroku

[https://feupscomputacionapp.herokuapp.com/][1]

All the routes work when going with the navigation of the page but when refreshing, entering manually or clicking back, the previous or current route is not recognized and an error "Can not get" appears

this is my app-routing.module.ts

  const routes: Routes = [
  {path:'',component:HomeComponent},
