Hello friends, I have simple API developed in Slim, which is stored in Online Server. It works fine when I check it from browser, but when I retrieve it from Iphone app, it show me the following error:

I tried a lot, but all in vain. If any one faced this problem, or know about this, then please guide me in this. Thanks in advance.

My code is given below

public/index.php

<?php
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;

require '../vendor/autoload.php'; 

$app = new \Slim\App; 

//Questions Routes
require '../src/routes/questions.php';

$app->run();

routes/questions.php

<?php
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;

$app = new \Slim\App;

//Get All Questions
$app->get('/api/questions', function(Request $request, Response $response){

$questions = "All questions are retrieved successfully";     

        echo json_encode($questions);

});

// Get specific Questions
$app->get('/api/questions/{app_id}', function(Request $request, Response $response){

$questions = "Specific questions are retrieved successfully";    

echo json_encode($questions);

});
