Neil Aspin said his players gave it everything after FC Halifax Town lost 2-1 to Harrogate at the Shay.
The visitors took a two goal lead after only 11 minutes but were then outplayed for long periods of the match as Town searched in vain for an equaliser.
The Town boss said his side did enough to win the match but and was left puzzled at how The Shaymen came away from it with nothing.
He said: “To concede two goals straight away put us on the back foot and we were then chasing the game all night, which meant the opposition could pack men behind the ball, sit deep and deny us space.
“We know the goals we gave away were poor but we had enough to win the game. We’ve hit the wood work three times and they’ve not had a shot at goal in the second-half.
“But it’s still hard to fathom how we haven’t won the game but to not even get a point is so disappointing.
“I’m proud of the players’ efforts, they’ve had a busy week. They gave everything tonight but they’re just unfortunate they haven’t got the result.”
Substitute Adriano Moke missed a golden opportunity in the last seconds when his close range shot hit the bar, one of three times Town struck the woodwork, before Gareth Seddon’s header went inches wide moments later as Harrogate somehow held on.
Aspin praised the visitors for their resolute defending but was left frustrated as his team failed to find an equaliser.
He added: “I don’t know how we didn’t score - it’s so frustrating. I’m lost for words really at the end. We’ve had a good six or seven games where results have gone well.
“Tonight we deserved better but we haven’t got the break and we’ve got to go again. We’ve suffered for the bad start and the two sloppy goals we gave away.
“On another day we’d have got the result. Harrogate put their bodies on the line and got some great blocks in. They worked hard to hang on.”
