title: Angular7: CanLoad Auth guard hangs browser
body: <p>I have created an AuthGuard Service and implemented CanLoad interface to it, as shown below</p>
  
  <pre><code>import { Injectable } from '@angular/core';
  import { CanLoad, Router } from '@angular/router';
  
  @Injectable({
    providedIn: 'root'
  })
  export class AuthGuard implements CanLoad {
    constructor(private router: Router) { }
  
    canLoad() {
      if (localStorage.getItem('isLoggedin')) {
        return true;
      }
      this.router.navigate(['/auth/login']);
      return false;
    }
  }
  </code></pre>
  
  <p>Below is my App Routing module</p>
  
  <pre><code>import { NgModule } from '@angular/core';
  import { Routes, RouterModule } from '@angular/router';
  import { AuthGuard } from './shared/guard/auth.guard';
  
  const routes: Routes = [
    { path: '', loadChildren: './layout/layout.module#LayoutModule', canLoad: [AuthGuard] },
    { path: 'auth', loadChildren: './auth/auth.module#AuthModule' },
    { path: 'not-found', loadChildren: './not-found/not-found.module#NotFoundModule' },
    { path: '**', redirectTo: 'not-found' }
  ];
  
  @NgModule({
    imports: [RouterModule.forRoot(routes)],
    exports: [RouterModule]
  })
  export class AppRoutingModule { }
  </code></pre>
  
  <p>No files are being downloaded when I check the browser networks tab and I see a blank white page and 
  Below is the warning I see in my browser</p>
  
  <pre><code>platform-browser.js:613 Throttling navigation to prevent the browser from hanging. See https://crbug.com/882238. Command line switch --disable-ipc-flooding-protection can be used to bypass the protection
