Unfortunately, such a situation sometimes may occur due to the instability of the server, or the player's internet connection.

In this case, please wait until the connection becomes stable, and try to open the game later. If the problem persists for a long time, please reach out to our technical support team.
Also, you can try to follow these steps:

1. Clear the app cache (on your device, go to settings -> apps -> My Cafe -> storage -> clear cache)
2. Change your internet connection (from Wi-Fi to mobile internet, or vice versa)
3. Reboot your device/router
