We are trying to setup php file into cron job in windows 8.1 system, to call GCM push notification and to get notification in our registerrd devices.
It works fine when we run cron using any browser like Chrome , Firefox then I get GCM push notification to my registered device but, If we try same configure using php.exe then we are not getting notification to our devices.
To schedule cron we are using Task Scheduler in that our trigger setting are like :-
And in our Action tab We have set up bellow lines:-
Program / script :- D:\xampp\php\php.exe
Add arguments (optional) :- -f D:\xampp\htdocs\PushNotificationSql\tasknotification.php
Start in (optional):- D:\xampp\htdocs\PushNotificationSql

After that We run manually then We get response as per below image but can not get notification into registered device.

Any help will be appreciate!
