The reason why you can't get into Donut City is due to server maintenance and network problems, as follows:

1. Donut City game is undergoing server maintenance or update, resulting in the inability to access or play normally, wait for the completion of the maintenance or update, and then you can enter the game normally.

2, geographical restrictions or network shielding caused by the inability to connect to the game server, this situation can be replaced with a network environment, waiting for the game server to return to normal and then enter the game.
