Stanley boss John Coleman branded Lukas Jensen's red card in the 3-0 defeat at Ipswich "a load of nonsense".
The goalkeeper was given his marching orders in stoppage time after bringing down Harry Clarke just outside the penalty area.
Nathan Broadhead, Kayden Jackson and Kyle Edwards were all on target for the home side.
Broadhead opened the scoring in the 12th minute, his fourth goal in four successive home games. He was in the right place in the six-yard box to steer home a cross from Jackson.
Mo Sangare was robbed of the ball by Janoi Donacien whose cross was headed towards goal by Freddie Ladapo but was held by Lukas Jensen, who then pushed away a first time toe-punt from the Ipswich striker.
At the other end Christian Walton was adjudged to have tipped a shot over the bar from Aaron Pressley.
Conor Chaplin had the ball in the net just before the half-time break but his effort was ruled offside.
Ipswich extended their lead in the 56th minute when Jackson converted after Luongo struck the bar.
“We are devastated with the sending off,” said Coleman. “It doesn’t make sense, it’s a load of nonsense. You’re looking for empathy from the officials, there was none tonight.
“We’re blighted with injuries and suspensions. We didn’t get a fair crack of the whip today, full stop.
“It’s going to be hard with the quality Ipswich have got, we give it our very best shot. We are loads of players down.
“I’m not saying the referee determined the game because they were better than us, they should be.
“It’s a circus when we go to a big club because what we do we get punished for, what they do they don’t. We were better tonight but we’re disappointed with the goals.
“We were thinking we’ll keep it at arm’s length for an hour and then we conceded what we think is a very poor goal, but we have given a spirited account of ourselves.”
