[Crash] I got kicked out of a game, and I couldn't reconnect

about 3 minutes into a beginner 3v3 bot game, I got disconnected, but my internet was doing fine. I waited a minute or so, then I decided to leave and reconnect. When I left the game, the client put me to home page, instead of giving me the option of reconnecting. On the right side, it also showed that I wasn't in a game. I could also start another game.

Not really sure what happened?
