Magento 2.2.5 | How to redirect page to payment gateway provider after clicking on place order, Custom Payment Gateway Module

Question

I am new to Magento 2 Platform and this my first project, I have some basic knowledge about Magento.

I am creating a custom payment method module and achieve the front end part means I can see the UI on admin and checkout also.

Steps I take.

Created a block

     class Main extends  \Magento\Framework\View\Element\Template
       {
        protected $_objectmanager;
       protected $checkoutSession;
       protected $orderFactory;
       protected $urlBuilder;
        private $logger;
       protected $response;
         protected $config;
        protected $messageManager;
       protected $transactionBuilder;
    protected $inbox;
       public function __construct(Context $context,
                        Session $checkoutSession,
                        OrderFactory $orderFactory,
                        Logger $logger,
                        Http $response,
                        TransactionBuilder $tb,
                        \Magento\AdminNotification\Model\Inbox $inbox
                       ) {


$this->checkoutSession = $checkoutSession;
$this->orderFactory = $orderFactory;
$this->response = $response;
$this->config = $context->getScopeConfig();
$this->transactionBuilder = $tb;
$this->logger = $logger;
$this->inbox = $inbox;

$this->urlBuilder = \Magento\Framework\App\ObjectManager::getInstance()
    ->get('Magento\Framework\UrlInterface');
parent::__construct($context);
    }

      public function _prepareLayout()
         {
        $method_data = array();
         $orderId = $this->checkoutSession->getLastOrderId();
         $this->logger->info('Creating Order for orderId $orderId == '.$orderId);
         $order = $this->orderFactory->create()->load($orderId);
       if ($order)
               {
             $billing = $order->getBillingAddress(); //get billing address
    $payment = $order->getPayment();
    $payment->setTransactionId("-1");
    $payment->setAdditionalInformation(
        [\Magento\Sales\Model\Order\Payment\Transaction::RAW_DETAILS => array("Transaction is yet to complete")]
    );
    $trn = $payment->addTransaction(\Magento\Sales\Model\Order\Payment\Transaction::TYPE_CAPTURE,null,true);
    $trn->setIsClosed(0)->save();
    $payment->addTransactionCommentsToOrder(
        $trn,
        "The transaction is yet to complete."
    );
    $payment->setParentTransactionId(null);
    $payment->save();
    $order->save();
    try{
        $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;
        $client_id = $this->config->getValue("payment/ndhk_pg/client_login",$storeScope);
        $client_secret = $this->config->getValue("payment/ndhk_pg/client_pass",$storeScope);
        $testmode = $this->config->getValue("payment/ndhk_pg/ndhk_testmode",$storeScope);
        $this->logger->info("Client ID: $client_id | Client Secret : $client_secret | Testmode: $testmode");
        $api_data['txnid'] = time() ."-". $order->getRealOrderId();
        $api_data['login'] = $client_id;
        $api_data['pass'] = $client_secret;
        $api_data['amt'] = round((int)$order->getGrandTotal(),2);
        $api_data['txncurr'] = "INR";
        $api_data['date'] = "INR";
        $string = $client_id.$client_secret.$api_data['txnid'].$order->getGrandTotal().$api_data['txncurr'];
        $hashkey = hash_hmac('sha512', $string, '35d97d4459ae1883cbd2bb8be644115');
        $api_data['signature'] =  $hashkey;
        $api_data['date'] = date('d/m/Y H:m');
        $api_data['mobile'] = "8446320942";
        $api_data['od'] = "Order Description";
        $api_data['ru'] = $this->urlBuilder->getUrl("ndhk/response");
        $this->logger->info("Date sent for creating order ".print_r($api_data,true));
        if($testmode){
            $api_data['actionUrl']  = "https://sandbox.abcpay.com/abc_Api/paymentRequest";
        }else{
            $api_data['actionUrl']  = "https://prod.abcpay.com/abc_Api/paymentRequest";
        }

        return $api_data;


    }catch(\CurlException $e){
        // handle exception related to connection to the sever
        $this->logger->info((string)$e);
        $method_data['errors'][] = $e->getMessage();
    }catch(\ValidationException $e){
        // handle exceptions related to response from the server.
        $this->logger->info($e->getMessage()." with ");
        if(stristr($e->getMessage(),"Authorization"))
        {
            $inbox->addCritical("NDHK Authorization Error",$e->getMessage());
        }
        $this->logger->info(print_r($e->getResponse(),true)."");
        $method_data['errors'] = $e->getErrors();
    }catch(\Exception $e)
    { // handled common exception messages which will not get caught above.
        $method_data['errors'][] = $e->getMessage();
        $this->logger->info('Error While Creating Order : ' . $e->getMessage());
    }
}
else
{
    $this->logger->info('Order with ID $orderId not found. Quitting :-(');
}

             }
             }

Created two controllers **1. Redirect/index.php
1. Response/index.php**

    protected $pageFactory;
     public function __construct(Context $context,PageFactory $pageFactory) {
        $this->pageFactory = $pageFactory;

        parent::__construct($context);

    }

    public function execute()
    {

Problem

Whenever I click on place order it takes me to ndhk/redirect and shows me the page in contents.phtml but it doesnot redirect me to payment gateway provider as written in contents.phtml and after sometime it redirects to homepage.

I do not know where i am doing wrong or what I should try.

Kindly help me if anyone.
