Hearthstone account stuck at "waiting for the opponent to reconnect"

Hello,
I was in a friendly tavern brawl, when my friend got disconneced and since then my account has been stuck on “waiting for the opponent to reconnect”. Restarting my game doesnt help it as well and it still takes me back to the same game where he disconnected from. However for him, this is not the case and his game works fine but he cannot rejoin that game.
Kindly look into it asap.

Thanks
