Device is not connected to a network

[daniel-ec]

When WiFi is enabled everything works as it should.

If I disable WiFi, or am out and about using carrier data, I receive an error saying Device is not connected to a network.

Have tried connecting to our own server and also demo.owncloud.org

Steps to reproduce

1. When using the app with a working account, ensure you are on carrier provided data service
2. Attempting to access any file flashes up a message saying either Device is not connected to a network or "It is not possible to connect to the server at this time."
3. Try accessing the URL from a Safari on the phone and all is OK.

Alternatively:

1. Delete account
2. Create new account using demo.owncloud.net
3. See the "It is not possible to connect to the server at this time." on the config screen.

Expected behaviour

It should connect and work!
