problem with ajax connections

good afternoon. my game through ajax communicates with the server. the server has an Access-Control-Allow-Origin policy: *

I exported the project and checked it on the local server, it exchanges data with the remote server, everything works. I build a project for android-ajax does not work with the remote server. I checked it in the android studio, and got this error in the logs: "[Construct 3] AJAX request to 'http: // ********' (tag 'Check_connect') failed: "

checked permissions by adding code like this:

var permissions = cordova.plugins.permissions;
permissions.checkPermission(permissions.INTERNET, function( status ){
 if ( status.hasPermission ) {
 console.log("Yes :D ");
 }
 else {
 console.warn("No :( ");
	permissions.requestPermission(permissions.INTERNET, PremmSuccess, PremmError);
 }
});
function PremmError() {
	//alert('NO');
}

function PremmSuccess( status ) {
	if( !status.hasPermission ) PremmError();
}

found the solution

request from android means like request from https site.if your server use http protocol-that is the problem.just use https,and don't forget change http to https in ajax request.
