Disconnecting mid game

My game started to disconnect mid game in a ranked game in my promos. Will i get a loss or get penalties for it? I was winning the game as well. There was a yuumi on our team. I tried f4 to try and rejoin but it gives me "Unable to connect to the server. Please chec your network connection and attmept to reconnect to your game." Anyone else experiencing this and is there a fix?
