my game got interrupted and couldnt go back to it

I am really triggered because of what happened to me today ...... i was in a ranked game and then somehow my game got interrupted ( my connection was good i tested it) so i did '' alt F4 '' to leave it . But when i tried to login again , instead of going back to the game ,it just sent me to the client's home page .The issue is , i could launch another game while the previous one was 100% still going on and it didn't even appear in my history. please riot find a solution for that ........ it is a ranked game
