Problems with NavController. It stops working correctly when I logout

Hello, I have an ionic app with login/registration + validation and a home with a couple of views.
The structure can be something like this:

steps

I don’t have any problem moving through the app, until I use the logout. When that happens when I register, I get to the validation page and when I get the response with the OK from the server I don’t get redirected to the home page. I also get adouble back button in my stacked views.

Maybe I am not cleaning something the right way. I don’t get any error, just everything stops working the right way. Can anybody help me with this problem?

Right now I am using Ionic 3.19.1. Just ask away if you need some more information.

This is my logout:

logout() {
        localStorage.clear();
        this.websocketService.close();
        this.close();
        this.navCtrl.setRoot('LoginPage');
        /* Testing porpose
        this.navCtrl.setRoot('LoginPage').then(() => {
            this.navCtrl.popToRoot();
        });
        */
    }
