Hughton could not believe his side had slipped to defeat.
"I am wondering how we got nothing out of the game," he said.
"We conceded two very poor goals in a game where I felt we were comfortable enough in the first half as the away side, and if our final pass had been better we might have been able to get another goal.
"At 1-0 we were comfortable but to give away the two goals we did, at the time we did, changes the atmosphere in the stadium.
"The crowd were fairly quiet in that first half and that was down to the effect we had on the game.
"For a side that had taken a knock like that we responded very well, but their goalkeeper, as he did at Carrow Road, made some super saves.
"We also hit the woodwork a couple of times and had a couple of goals disallowed. So I cannot fault the desire and effort of the players to get the goals and we missed some chances, but how we did not win that game I do not know."
