League server disconnect for everyone and I don't get any rewards for leaving

Ok so I just got off a 30 minute game of tristana where my score was 13 2 5 in the end, I'm dominating laning phase then riots servers shut down, I reconnect and fight the few enemies that are connected on the enemy team with my lux and tahm, and after 30 minutes of slowly pushing in the end it says I can't gain a hextech chest because i went afk and i didn't get my daily win or any xp, it feels terrible to have wasted 30 minutes for not even a single xp point
