Welcome, and thank you for becoming a member of the King Community! I will be very happy if I can help you.
According to your screenshot, the Internet is disconnected while playing the game, or the Internet is slow. Wait for some time in this situation and try again. It will remain there until you find something.
You check if your game is connected to the server.
Or try Log out game > Restart your device > Open game & Log in again.
If you have any questions at all, I’d love to hear from you. Simply reply back to this post, or send me a message.
Have a good day.
