[CLIENT] logins creen timer, acepting a match and champ select bugs EU Nordic and east

first of all very frequently these past 2 days sometimes 9 out of 10 times the game doesn't log me in and i restart lol and try again and after many tries it logs me into my account. after that i queue for a match but then i press accept i see one person has accepted an no others it doesn't register me or the other players accepting also if i didnt accept it should kick me and go me to a lobby but it isn't. finaly at champ select the selection timer is too slow or sometime ti doesn't register my clicks at all and it crashes near the last pick or when the loading screen should pop to let us load for the game.I think the client may have a prob or the server or something . i have been playing 2 years lol and now this happens .... this started to happen after the 5.20 patch.Something is wrong plz fix this thanks for your time
