Ranked Games

So ever time I get into a normal game of league of legends I have no problem loading into the game, I legit can play anything, aram, twisted treeline, TFT, but when it comes to ranked solo/duo or flex it continues to tell me I need to retry loading into the game, I have had this happen to me so many times last few days, or ever sense TFT has been released, The game is not being fixes I feel.
