Well i am securely connected to the internet, but then the game says no internet. That time was the heroic race of the high queen dragon. So i just lost my progress even I am lv30.............

Unfortunately this is an issue with your wifi connections not the game. Have you tried a different platform? Or turning off your wifi and reconnecting?

Yeah, i did. No use....

@HowardNg Then I suggest you try sending in a ticket to support. I am not sure how much help they will be since this is not the game but it is worth a shot.

Thanks for the help!
