League Of Legends won't let me reconnect Mac

Whenever I play on a Mac I get this every like 20 games where I dc at 30 ping and it crashes so when I try to reconnect it won't load and soon after trying to reconnect countless amount of times I simply can't go back and it just lets me into the lobby and join another game. Please fix this I keep getting leaver buster because of this and it annoys me.
