In game but can't get back in?

I am not quite sure exactly what happened, I was playing a match (and its still going right this very moment) but, in the middle of the match I got the " please wait a moment while you are reconnecting" message... So I waited a moment then I opened my browser thinking it might be my internet and searched to see if I got any results I did. So I decided to exit the match . When I exited the match it took me to the main screen and the play button lit up again so I could basically get into another game... So I restarted my client to see if it would let me back into my match but, it didn't. It isn't saying anything it doesn't even show up that I am in a game on league but, on websites like op.gg it says my match is still going? I am probably gonna lose my LP for this so sad :(.
