Meteor cordova turn white screen when offline

My meteor Cordova app will turn white screen when there is no internet connection. i want to copy my code here too but i still don’t know what is the problem that causing this. the only two cordova-puligins i add is cordova-plugin-meteor-webapp@1.4.1 phonegap-plugin-mobile-accessibility@1.0.5 The app will work just fine when there is internet connection.
