I can login just fine bro. Maybe your region is blocked. Refer to the message below by another user.
One more test :
You all can't login with Facebook,they blocked Facebook app in their country ( i know they very restricted with FB,Twitter etc app from outside their country
LOL )
Easy method to login use email,use fake email or fake GPS (if you can't login,but only work in some device or rooted phone)
Have a nice day
Note : All game that related with the country will be block by IP Address soon or later
All game that related with history of
"Three Kingdom" is very restricted
Believe or not i am just give you all some information,that's all
