Not able to launch iOS app due to Failed to load webpage with error: 999 error

Hi Developers,

I am using ionic 1 and Angular JS to develop the application. While installing build in iOS I am getting an issue like Failed to load webpage with error: The operation couldn’t be completed. (NSURLErrorDomain error -999.). When I launch the app in iOS simulator I am seeing a blank white screen with a loading indicator. How do I solve this issue. Can someone share a possible solution.

And also I am using html5 input type="date" to display date picker. In iOS 14.x the date picker is displayed as Text field.
