ACCOUNT PROBLEM? OR CLIENT PROBLEM?

I DO NOT KNOW HOW TO REPRODUCE THIS BUG, BECAUSE IT IS MY FIRST TIME TO FACE THIS KIND OF BUG I WAS PLAYING ARAM. AND SUDDENLY GOT DISCONNECTED. AFTER THAT I CANT RECONNCET SOMEHOW TILL NOW. IT SEEMS LIKE THE GAME WILL NEVER END THEY HAVE BEEN PLAYING 4V5 ARAM FOR 57MINS. SO I ASKED MY FRIEND TO SPECTATE MY GAME TO SEE WHATS GOING ON, BUT HE SAID IM NOT IN GAME? PLZ RITO HELP ME. IM HOPELESS. PS. IM NOT SURE IF THIS IS THE RIGHT THREAD. IF I AM WRONG SORRY, AND GUIDE ME PLZ THX.
