Ionic 3 Http get request - null response iOS only

[wf9a5m75]

HTTP request issue on IOS : Always return null

CORS issue should not happen on Device. Add <allow-navigation href="*" /> on your config.xml and see if its working. Note: Make sure cordova whitelist plugin is installed.

HTTP Request ends in Status:0 for URL: null

had to add this in my webserver php files… header("Access-Control-Allow-Origin: *");
