DNS Support for IOS 11 for app developed with Adobe Flex & Air

Hi,

I recently updated my AIR SDK to support the application developed with flex & air for iOS 11. In my app, earlier i used to connect to login with DNS name. It was working fine. After upgrading the sdk, i am not able to login into the application, I get "#2032" error in mobile device. But if i run it from AIR simulator from flash builder it works fine. Is there any thing i am missing for ios11 ?
