[Client] Why do I have to reconnect to a custom game I just created and quit?

I always create a custom game with Bots to check my ping before playing with friends. This used to work fine for me. But now I have noticed that every time I dodge an custom game, the client shows a reconnect button and force me to reconnect to the game. So that I have to close the client and log in my account again. Sometime even though I restart the client, I still get reconnect button after I logged in.
