Angular Not Redirecting After Getting Auth Token

Dear Experts Angular, Please See The Code Below And Tell Me Is It Correct or Wrong ?

  onFormSubmit() {
    this.isLoadingResults = true;
    this.authService.login(this.loginForm.value).subscribe(data => {
        this.isLoadingResults = false;
        this.router.navigate(['/secure'],{ replaceUrl: true }).then(_ => console.log('You are secure now!'));
      }, (err: any) => {
        console.log(err);
        this.isLoadingResults = false;
      });    
  }
