The Ghana international struck a long-range curling effort after coming on as a 46th minute substitute but his goal was not enough to save the Men in Red from a 2-1 reversal.
"I just wanted to give the team energy," Accam said, according to his club's official website.
"I came on with positive energy and tried to go forward a lot. Luckily I got a goal.
"It's not them. It's about us. We were really slow. I don't know what happened but we didn't pass the ball faster, we kept moving the ball backwards.
"I don't think they played really well but they took their chances and we just didn't play at all.
"At the end, we started getting better but it was too late for us. We should have done that earlier in the second half."
The loss saw Veljko Paunovic's outfit's 11-match unbeaten run in MLS come crushing.
"We will lose games, that's part of the game," Accam said.
"We have about 14 games more to go. For us, we will try to take the next game and win it. It's part of the game to lose.
"The way we react in the next game is more important, so we need to be sharper and try to win the next game."
Accam has netted 11 times in 18 league games so far this season.
