F5 doesn't work RIGHT on my webapp - html

Question

i have a strange problem:
we have to make a project in IT, therefore we use AngularJS.
The problem is, when I use F5 for refresh, the page loads, but it is not able to show the right content again. There's just background and my title, everything in my UI-VIEW isn't there.
We have Login-Page with redirecting:
app.run(function($rootScope, $location, sessionFactory) {
$rootScope.$on('$stateChangeStart',
function(event, toState, toParams, fromState, fromParams){
let loggedIn = sessionFactory.isAuthenticated();
if (toState.authenticate && !loggedIn) {
event.preventDefault();
$state.go('login');
}
});
});
without this redirecting block, F5 works.
Otherwise I have to go to Login-Page and login again to get it work again.
I'm sorry guys, I'm new at programming. So if there's any code you need, just let me know. Hope someone can help.
UPDATE: this is our authentification_service.js
a group member wrote it. Does it help?
var app = angular.module('TheApp');
/**
* This service manages sessions: Retrieving token from server and storing token data.
*/
app.factory('sessionFactory', ['$http', 'jwtDecoder', function($http, jwtDecoder) {
var sessionFactory = {
sessionData: null
};
sessionFactory.login = function(username, password) {
//todo: encrypt password....
var user = { username : username, password : password};
// returns a POST request, success or error of that request
// must be handled by the caller of the login function
return $http({
method: 'POST',
url: 'rest/auth/login',
data: user
});
};
sessionFactory.logout = function() {
return $http({
method: 'POST',
url: 'rest/auth/logout',
data: this.sessionData
});
}
sessionFactory.deleteSessionData = function() {
this.sessionData = null;
}
sessionFactory.setSessionData = function(sessionData) {
this.sessionData = {
token: sessionData.token,
userData: jwtDecoder.getUserData(sessionData.token) // holds user id, todo: permissions
