Remake feature did not work

At the start of the game, our Pyke support disconnected. This was within 5 seconds of loading into the game. When 3 minutes approached, we attempted to /remake, but it stated that a summoner needs to be disconnected in order to remake. There was no point within that 3 minutes where the Pyke reconnected/disconnected again, so I am very confused on why we were unable to /remake. Needless to say, we lost the game. The other team got a free win, and our team got a free loss. It's really upsetting that this happened. Thanks for the help.
