Game won't connect in champ select

I was trying to play a game of nemesis draft with a group of three when the game refused to allow me to connect to the lobby which automatically caused me to dodge and receive a penalty. This silent the first time i have either experienced or seen this happen and it is rather unfair to be punished for something that i have no control over, the internet was working just find however the lobby refused to load. If i could get some clarity or a resolution so that this does not happen again again that would be fantastic.
