DC'ed and can't get back into ranked game upon relogging

I recently DC'ed from a rank game and when i tried to relog it took be back to the home page with no access to the ranked game. I will probably obtain 4 afk reports from this (at minimum). How do you eliminate this glitch for future purposes? (And please don't be a child and put down have better connection because that was the first DC i have had in months!)

Thank you for the help!
