Sometimes, though rarely, I experience an issue where Ubisoft network becomes offline and I get disconnected from the game.
My internet connection is stable and connects fine to ubisoft servers while in other games.
So the problem is that the automated system instantly gave me a penalty without letting me restart the game and reconnect (without even a timer).
The system could not detect that it was network issue with the servers and that I did not abandon the game through the UI menu.
This all happened in a course of 15 seconds; the match was just starting.
