Hard to login

[iMilo]

From maybe 2-3 days ago i started to failed connect to the server..
If i can, mostly will lagged so much like freezed until 1minutes or more
I don't download anything or open any web..
My internet connection good and when i tried to open other website, it can open fast..
So just have problem to get to the server just every night

Can someone can help me fix this??
