Ionic 4 Nav Push not pushing Page

Ionic Framework ionic-v3
1

While developing a new (tabs based) ionic app, i tried to push a new page. I already tried this.navCtrl.navigateForward(MyComponent) and this.router.navigate(['tabs','my','component']). I injected the Router (or NavCtrl) in the constructor and made it private.


@Component({
  selector: 'app-stream',
  templateUrl: './stream.page.html',
  styleUrls: ['./stream.page.scss'],
})
export class Component {
  constructor(
    private router: Router,
    private navCtrl: NavController,
  ) {
  }

 public navigateRouter() {
  this.router.navigate(['some', 'url'])
 }

 public navigateNav() {
  this.navCtrl.navigateForward(OtherComponent)
 }
}

In both cases, the URL gets updated, but the page component wont be displayed.
This is an example, the real app could be found on github (currently in the feature/stream branch)
Git (Fixed commit)

I’m actually not so sure about my routing (anymore).
My goal is to have /tabs removed in the URL and have routes like:
/stream
/stream/locations/:locationId
/tab2
/tab3

src/app/app-routing.module.ts
src/app/tabs/tabs.router.module.ts
src/app/tabs/stream/stream.module.ts

The red circled route is the route that i want to navigate to, but isn’t loaded

Any help is appreciated.

PS: i also tried the directive routerLink="MyComponent" in combination with routerDirection="forward"

Edit:
