An image of the 902 error message.
902 error messages will appear when your device isn't able to connect to the Hempire server. This can happen when the server is particularly busy, usually if a lot of players are downloading a new update at the same time, or if your wireless signal is currently experiencing disruptions. Most 902 errors will resolve themselves after a few hours, so try connecting to Hempire again later and see if it works for you then.
 
If the problem persists for longer than a day then please contact our support team. (you can contact it from the loading screen by using the ( ? ) question mark icon in the top-right corner of the loading screen) Please include a detailed explanation of what is happening when you try to load the game.
