My game cannot run last day what is the problem ?

Game servers are working. Is the app lot running for you or are you getting time out messages when trying to connect? If its a time out then you must be having trouble connecting to the game server yourself. Perhaps a network issue with your device or connection?

If the app isn't running them you may need to reinstall it. Al;though make sure you have successfully bound your game to an external account first.

If this doesn't help then you can try contacting support to see if there are any issues with running the game on your device.
