How to access intranet sites from web view on Mac

I am using Xamarin.Forms in mac and I am not able to access our corporate intranet site from WebView control. The same url works fine in Safari or chrome and the same code for uwp also works in windows(After providing access to Private Network). I searched for a solution and made some changes in info.plist but still the issue persists. Would greatly appreciate if somebody could help.
Sample url that did not work is an https url
I am able to access internet sites from WebView.
I am facing the same issue using simulator for android or ios.
