*Reconnects* "Due to prolonged inactivity your game will now exit" WTH!?

So basically these past couple months when I'm in game (usually ranked) I would get disconnected from Riot's servers (I made sure that my internet wasn't the problem) then I would reconnect, BUT once I get back in game it says something along the lines of "Due to prolonged inactivity your game will now exit." then it would exit my game back to the reconnect screen, and the process repeats over and over. I've been put on a 10min lower priority queue now because of this happening near the end of games (so when i reconnect its over and considers it as a "leave").

Any fixes?

I play on Mac OS X Yosemite Version 10.10.2
