You can also use hash-based navigation by including the following in app module ts  import   LocationStrategy  HashLocationStrategy   from   angular common     and by adding the following to the  NgModule            NgModule           providers             ProductService              provide  LocationStrategy  useClass  HashLocationStrategy                              HashLocationStrategy   A hash sign     is added to the URL  and the URL segment after the hash uniquely identifies the route to be used as a web page fragment  This strategy works with all browsers  including the old ones      Excerpt From  Yakov Fain Anton Moiseev     Angular 2 Development with TypeScript

Check your index html  If you have accidentally removed the following part  include it and it will be fine    lt base href     gt    lt meta name  viewport  content  width device-width  initial-scale 1  gt     lt link rel  icon  type  image x-icon  href  favicon ico  gt

https   angular io docs ts latest guide router html     Add the base element just after the  lt head gt  tag  If the app folder is the application root  as it is for our application  set the href value exactly as shown here    The  lt base href     gt  tells the Angular router what is the static part of the URL  The router then only modifies the remaining part of the URL    lt head gt     lt base href     gt         lt  head gt    Alternatively add      Angular2 RC 6  import  APP BASE HREF  from   angular common     NgModule     declarations   AppComponent     imports   routing    or RouterModule         providers    provide  APP BASE HREF  useValue                 in your bootstrap   In older versions the imports had to be like   lt  Angular2 RC 6    import  APP BASE HREF  from   angular common   bootstrap AppComponent      ROUTER PROVIDERS      provide  APP BASE HREF  useValue                   lt  RC 0    import  provide  from  angular2 core   bootstrap AppComponent      ROUTER PROVIDERS     provide APP BASE HREF   useValue                   lt  beta 17    import  APP BASE HREF  from  angular2 router        beta 17  import  APP BASE HREF  from  angular2 platform common     See also Location and HashLocationStrategy stopped working in beta 16
