Wrexham missed out in front of the BT Sport cameras as previously winless Maidenhead United claimed all three points at the Racecourse.
Josh Coley’s first-half header was enough for the visitors, as Jordan Ponticelli had a late equaliser chalked off for offside.
Dean Keates made two changes from the side which beat Yeovil just two days earlier, with Jordan Ponticelli in for his first league start of the season.
Elliott Durrell also returned to the starting line-up, with Paul Rutherford and the injured Anthony Jeffrey dropping out.
Adi Yussuf returned to the bench after his own injury, meanwhile, and James Horsfield was back in the 16 too.
It was perhaps a consequence of the quick turnaround between matches, but neither side set a fast pace in the early exchanges.
Rob Lainton dealt with some balls into the box comfortably and Elliott Durrell’s corner came to nothing at the other end with chances at a premium.
Wrexham’s first opportunities fell to Jordan Davies, whose long-range shot was blocked on the quarter-hour and another in similar circumstances two minutes later.
The latter led to a big penalty shout as Davies got to the rebound, beat his man and was blocked off, but the referee was unmoved.
Luke Young then had a big chance on 19 minutes, after Reece Hall-Johnson was tripped on the edge of the box, but his free-kick clipped the bar and bounced over.
Shaun Donnellan stung Lainton’s palms at the other end on 29 minutes, after good work from Remy Clerima.
But Maidenhead’s goal was against the run of play when it did arrive – Donnellan crossed for Coley, who headed in from close range on 33 minutes.
Ponticelli and Harris both missed the target at the other end as Wrexham searched for an immediate response.
But it was the visitors in front at the interval as Wrexham too often struggled to make Taye Ashby-Hammond work.
Maidenhead should have doubled the lead after the break but, unmarked, Clerima could only head straight at Lainton on 48 minutes.
At the other end, Kwame Thomas headed wide after excellent work from Elliott Durrell on 56 minutes, but Lainton had to be alert to deny Donnellan after an underhit backpass moments later.
Luke Young’s perfectly-weighted lofted through ball presented Ponticelli with a great chance behind the line on 62 minutes, but he headed wide.
Dean Keates made his first two changes two minutes later, as Rutherford and Yussuf replaced Jay Harris and Thomas.
Yussuf was quickly in the thick of it, working the ball into the area for Ponticelli on 68 minutes but, after turning well, his shot was straight at Ashby-Hammond.
Two minutes later, Young tried to catch the goalkeeper out from a deep free-kick, but Ashby-Hammond punched the dipping effort clear.
Ponticelli thought he had levelled on 80 minutes, firing high into the net after Yussuf kept the ball alive in the area, but the linesman’s flag was raised.
Rutherford then had a penalty shot turned down in the 89th minute, after he appeared to have his shirt pulled trying to run on to Yussuf’s ball on.
In the second of six minutes added on, there was another big shout for a penalty, for handball, as a header goalward was blocked. Again, however, the referee was unmoved.
Maidenhead cleared the subsequent corner and were able to run the ball into the corner to eat up more valuable time.
And the visitors were able to stand firm to claim all three points on a frustrating night at the Racecourse.
