Costant "Unexpected Disconnection Occurred" in PoE2

Hi, as title, since yesterday I was unable to play because every 30-60 second the game keep kicking me out with the "Unexpected Disconnection Occurred" error.
I think it's graphic related because it's get significaly worse when I cast a lot of spell with strong visual effect, but I cannot be sure.
In any case I cannot stay in game for more then 3 mins top.
I wanted to signal this issue while I'm waiting for the next patch.
Thanks for the attention and sorry for my broken english.
