angularjs html5 hash url

Question

I am using server side google oauth in angular.js,

Suppose my redirect url is localhost:8000/redirect. To remove # in angularjs I am using

$locationProvider.html5Mode(true);

But, when i visit the url I get an error :

Error response

Error code 404.

Message: File not found.

Error code explanation: 404 = Nothing matches the given URI.

However if I type the url manually i.e localhost:8000/#redirect then I get what I expected and then redirects to localhost:8000/redirect

I have also tried to add # from Google app console. But, that is not allowed.

So how to remove hash completely ?
