Unable to login in magento admin panel in any browser

Question

I am unable to login in magento admin panel. Magento ver. 1.9.2.4. Reason is in every minute its calling this:

Error : {ajaxExpired: 1,…} ajaxExpired : 1 ajaxRedirect : "https://www.gleitsichtbrille.de/index.php/ag_supervista/index/login/key/dc32322811d123b75356a152194991d0/"

I have followed below steps to solve this error:

1. Clear browser cache, history,etc
2. Delete cache folder from var.

3. checked with below code to comment it in app\code\core\Mage\Core\Model\Session\Abstract\Varien.php and remove cache:

   // session cookie params
   /*$cookieParams = array(
       'lifetime' => $cookie->getLifetime(),
       'path'     => $cookie->getPath(),
       'domain'   => $cookie->getConfigDomain(),
       'secure'   => $cookie->isSecure(),
       'httponly' => $cookie->getHttponly()
   );*/
   

4. Set Permission 777 to cache and session folder.

5. Set web configuration "Use HTTP Only" to "No".

My issue is solved now!!!

I have deleted Application Load Balancer from AWS EC2 and followed below steps to create Classic Load Balancer with cookies 3600 as same was in my magento site.

• Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

• On the navigation pane, under LOAD BALANCING, choose Target Groups.

• Select the target group.

• On the Description tab, choose Edit attributes.

• On the Edit attributes page, do the following:

• Select Enable load balancer generated cookie stickiness.

• For Stickiness duration, specify a value between 1 second and 7 days.

• Choose Save.
