"Unstable connection" in rivals

I am not sure why but in all online modes(rivals,friendlies etc) except rush it says unstable connection(which makes it unplayable), despite previous games(fifa) and different other onlines games not having issue with ping. I am not sure if its a server issue,like connecting to different one (which shouldnt happen), or its a general issue. Generally makes FUT not as fun cause rivals andthe other modes are the main point of it.
