$http.post does not work in ionic android app

I am experiencing very strange issue when building and running ionic app. I am calling Login API from server and it work very well in browser, when run as

$ionic serve --lab

But when app is installed in Android, it gives 403 error, and does not give any other information about error code, probably, i am not sure how to get browser console log in android hybrid app.

I have login function as follows

 login: function(user) {
            var deferred = $q.defer();          
            $http.post(SERVER_URL + '/auth/login', {
                username: user.username,
                password: user.password
            }).success(function(response, status, headers, config) {

                if (response.data && response.data[0]) {
                    Auth.setToken(response.data[0].token);
                    Auth.setUserId(response.data[0].id);
                    deferred.resolve(response);
                } else {
                    deferred.reject(response);
                }
            }).error(function(response, status, headers, config) {               
                deferred.reject(response);
            });

            return deferred.promise;
        }

However, all the get request works properly.
