Not sure if this is a InAppBrowser bug or iOS but I've got the following situation in my app:
1. Starting my app with the InAppBrowser plugin and opening a webpage (Network connection gives a "Network Wifi" status, which is correct)
2. Turning on airplane mode (Network connection gives "No Network connection" status, which is correct)
3. Turning off airplane mode and running InAppBrowser again (Network connection gives "Unknown network connection")
For some reason the App doesn't get a valid connection anymore and the loading of the URL in the InAppBrowser plugin fails because of no connection.
This problem only applies for iOS, Android handles it correct.
Another app of me, which doesn't have the InAppBrowser plugin handles the connection correct as well
