Keep getting disconnected in friendstory

I'm at the story with that handsome teacher and i'm now at the part where you have to go through 3 stages of monsters at the sunset lot to get to him.
But i keep getting disconnected several seconds after entering. If i'm lucky i can get to the 2nd stage or even the 3rd stage but it always ends in monsters and skills not responding and finally a disconnect.

Did anyone else have this problem and a possibly fix (like not doing certain actions which will cause the crash).

Thanks in advance.

EDIT: I forgot to mention i had the same problem in the other stages and in cosmos knockout
