[CRASH] Can not leave the custom games

I played a custom game to practice with bots, then I left the game. After I left, It showed I have to reconnect to the game, so I click the reconnect to back in the game. I can not back in the game because it said there is a server error and I need to check the firewall. I used to play custom game to try new hero, so I know it shouldn't show the reconnect after I quit. Now I can't play other games and stuck in the reconnect page. My friend can't invite me because it said I'm in the game.
