Page reload fails when using Angular Ui Router with Html5 mode enabled


I am using Angular UI Router in my angular app and i have enabled HTML5 mode to remove the # form the URL by using $locationProvider in the config.

var app = angular.module('openIDC', ['ui.router']);
app.config(function($urlRouterProvider, $stateProvider, $locationProvider) {



    .state('home', {
        url: '/',
        templateUrl: 'views/home.html',
        controller: 'HomeController'
    .state('login', {
        url: '/login', 
        templateUrl: 'views/login.html',
        controller: 'LoginController'

I have also set the <base href="/" /> tag in the index.html file as well. The routing works fine and i can navigate to pages and the # is removed but when i refresh the page using the reload button on the browser there is a 404 error response.

enter image description here

Why is this happening and how can i fix it and have HTML5 mode enabled to have proper URLs


Kasun, the reason that this is occurring is because you are trying to refresh the page from one of your sub routes (has nothing to do with ui-router).

Basically if you request you likely have your server setup to return index.html which bootstraps your angular app. Once the app has loaded, any further url changes take html5Mode into consideration and update your page via ui-router.

When you reload your page the angular app is no longer valid as it has not loaded yet, so if you are trying to load a sub route (for example:, then your server does not know how to deal with /someotherpage and likely returns 404 or some other error.

What you need to do is configure your server to return your angular app for all routes. I primarily use node/express, so I do something like:

app.get('*', function(req, res, next) {
    // call all routes and return the index.html file here

Note: I usually use something like this as a final catch all, however I also include other routes above it for things like requesting static files, web crawlers, and any other specific routes that need to be handled.
