constantly disconnect

Hello first of all sorry for my english is not my mother language.
As the title says im getting constantly disconnect when ever i log in to the game i can stay logged in like 3-4 seconds then disconect.

I allways played with the HotSpot from my mobile since heres not good internet on my town. playing a year like this never had lag or disconects but this started today with no reason it started to disconnect when login 3-4 seconds then disconect.


Thanks in advance Jiju's
