What we would need here, is to do NOT redirect, if the state TO is already the ‘login’.
Just a drafted adjustment would be
$rootScope.$on( '$stateChangeStart', function(e, toState , toParams
, fromState, fromParams) {
var isLogin = toState.name === "login";
if(isLogin){
return; // no need to redirect anymore
}
...
And also, we should call $state.go('login');
with the event.preventDefault();
...
// also prevent default on redirect
$state.go('login');
event.preventDefault();
...
