couldn't connect to facebook

from yesterday i couldn't be able to connect the game with facebook. first i thought it was because i hadn't updated the game to the recent version. but today even after updating the Candy Crush Saga, the same issue isn't solved. tried many ways like: 1. deleted app from facebook and reconnected, 2. deactivated facebook and reconnect again, 3. switching the phone on/off severals. but nothing helped. previous messages of games are shown, even i could claim sugar drop rewards too. but every time while connecting to facebook, it shows cancelled. will be very graceful to get helped from you guys....please....
