I can see the internet is not working on your device. I'm asking you to check out some more troubleshooting.
Update the device software
If there is a software glitch, you can get rid of it by installing the latest software version. A new version will improve the overall performance of your device and its security and it will also bring bug fixes. If you didn’t enable automatic updates on your device,
you can see if there is an update manually:
Go to Settings
Scroll down and tap About device (About phone, About tablet)
Tap Software Update or System update.
Check App Permissions
Check App Permissions
When you give an app access to your Facebook account, that access expires after 90 days. The app then loses access to your account, which may affect your progress and friends list.
You can check which apps are active, expired or have been removed from your account by clicking this link: https://www.facebook.com/settings?tab=applications
If the game is listed as ‘expired,’ it means your friends list and progress may not sync with the game.
Click ‘Renew Access’ to reactivate the app’s permissions.
You might also want to check your active app-permissions by clicking the ‘view and edit’ link.
Remember, you'll have to do this every 90 days.
Let me know.
