Jackett said: "I talked before the game about our away form. There have been too many games where we hadn't put a performance on. As a player and as a group of players you can't guarantee a result because you can come up against officials like we did in this game.
"I felt that both sort of penalty incidents, you usually get one of them, you very rarely get two. To send the guy off looked soft."
Jackett is confident his side will soon be able to replicate their home form on their travels.
He said: "We have shown what we are about at home and played very well. Away from home, for me, we just haven't done enough. I challenged the players to put that type of performance on. Now we have to maintain that and keep that up. If we do that then generally results follow.
"It was a good performance and I was pleased with that because they have been few and far between for me away from home."
