"Connection timed out" is an expected behavior in a network environment. It's even more expected in a mobile environment, where network connections can be unreliable. It means that the server failed to respond for a certain number of seconds.

Because it's normal behavior, you'll need to handle it in your android application. Either attempt to retry, display an error message to your user, or do something else appropriate.
