No connection

Hello everybody! Since yesterday I cannot connect with King on my android tablet anymore and my progress isn't synchronized anymore. I cannot log in and it says there is no internet connection found (the dutch text in red on the screenshot), but everything is working normal on my tablet, except Candy crush saga and soda. All updates are installed, so please can you tell me what is wrong? On my android phone CCS works good and there I am logged in at King, but it doesn't synchronize with my tablet anymore. Hope you understand my problem and also hope there is a solution for this problem.
