Connectivity timeout in loading screen [Client]

I was in the loading screen for league and after several minutes I got a message pop up stating that I lost connectivity (even though I know I didn't. I'm streaming music and browsing sites and everything's flawless). But right after I click OK, it pops over to a remake screen tagging me as a leaver. For some reason the game didn't load past the loading screen. This just happened about 5 minutes ago.

Anyone else hear of this?
