Sorry for the inconvenience.

The game server is not stable recently, and our technical department is trying to fix the issue. By now, the server works fine, and you can restart the game to try it again.

What's more, the server might be not quite stable recently, so if it happens again, please try it patiently after 1 or 2 hours. And DO NOT uninstall the game or you may lose your game progress. If the game doesn't work well for more than 2 hours, please contact and let us know.

Thanks for your understanding and kind support!
