Andri Gudjohnsen nodded the hosts ahead and a second goal put Tony Mowbray's side in command as they went on to win 2-1.
There was some controversy though, with Yuki Ohashi's aerial challenge on Max Kilman waved away by the referee moments before Dapo Afolayan fired into the corner.
Parker felt that was a foul but conceded his side should have also done better.
"First and foremost, we’re disappointed because the result wasn’t what we anticipated or certainly what we came here for," Parker reflected.
"I thought in the first half, we dominated for large parts without really posing too much of a threat. I thought we played the game in their half, which is exactly what we wanted to do.
"In the second half, we came out of the traps and started really, really well, and were dominant. Then, obviously, we weren’t clinical in our moments, and didn’t manage to get our noses in front, and then we get hit on a transition. They score, and that gives us a bit of a hill to climb.
"I think their second goal was a foul, but you can’t concede a second goal as quickly as that, because all of a sudden that hill becomes a mountain.
"I thought we pushed, and we obviously got back into it, but ultimately it wasn’t enough."
"I think there were elements that were good today, having only been here for two days, and one short training session yesterday, but fundamentally we lost the game, so it doesn’t sit well," he continued.
"There’s loads for us to work on - loads of different things - and we’ll do that tirelessly to get this team to where it needs to be.
"Like I said the other day, we can’t just concede goals and expect to score more to win a game. It’s the same no matter what league you’re in - if you give teams goals, it’s always going to be a hell of a challenge.
"We know we need to fix that, and we’ll work tirelessly to make sure we do that."
