That can be very usefull, lot of people uses /quit de disconnect from the server, and it’s shown as Timed Out, that could be usefull to trigger if a client as crash or not to “reserve” his slot when the server is full …
… but there’s no /quit command in the stock game chat?
In the console when you write quit, that make quit the game but not like an Alt F4 or something else, it’s write Timed Out in the reason because the link with the server is not close correctly
Idk if this can help you but check out this
