I get greeted with a black screen a lot saying please try again even though my connection is fine

In most games recently i have been kicked from league saying please check your connection and retry, it is annoying because even though i try to reconnect i get into game after somehow fixing the glitch and by then they remake and i lose lp for no reason this happens to me and my friends all the time even though our internet is fine and works with all over games and communicating over discord, i am scared to get demoted back to silver as this happens on a daily basis now. rito please fix this
