Based on your description, I assume that whitelisting for iOS isn't configured in your application.
Apache Cordova 4.0 and above incorporates the Apache Cordova domain whitelisting—a security model which provides a configurable security policy to define which external sites may be accessed. To enable whitelisting in your iOS application and allow HTTP/HTTPS request the app:
- Open the iOS Config.xml file in your project, as described here.
- Follow the steps outlined in the official Apache Cordova Whitelist Guide.
If this does not help, I order to continue my investigation, I will need a sample application that clearly reproduces the issue. I'd recommend that you open a support ticket, which is private and comes with a guaranteed response time and share the requested application there.
