Please help

Welcome to the King Community.

We are sorry for your trouble. App error or or several other reasons can also cause game connection problem.

As per your screenshot it is clear your game app has error and you can solve this problem by reinstalling the game app but your stored boosters will be lost.😔

We look forward to your reply and have a nice day.

Thank you.

Uninstalling the app will delete your game data unless you saved the game via Facebook or Kingdom.

If you saved the game through Facebook or Kingdom, you can log into the game using that ID and your game progress will be restored, details HERE.
