Wingate & Finchley suffered a double blow in the first-half against Horsham at The Camping World Community Stadium, and despite clawing a goal back midway through the latter stages, could only leave fruitless in a 2-1 defeat.
Within three minutes, Steve Metcalf found Charlie Harris, who placed with ease into the corner from inside the box to hand the hosts the lead.
Ahmet Rifat responded positively for the Blues when he won possession and played Tage Kennedy away down the left, who despite breaking into the box, dragged his shot wide seven minutes on. Tanasheh Abrahams needed to head away Chris Smith's dangerous cross to the far post, with Kieron Pamment in wait on 18 minutes.
Three minutes later, Luke Ifil looped in a cross almost finding Kennedy to guide home from close, but Joe Shelley cleared with a vital touch.
With 27 minutes gone, Harris pinged a perfectly-placed cross towards Pamment, who found Smith inside the box to tap home and double the trouble.
Shane Gore had to be alert on 41 minutes with a strong save down to his near-post, following a recycled move between Smith and Harris. Ifil's whipped cross arrived at Kennedy, who set-up Tommy Tejan-Sie on the edge of the box, but he powered wide on 44 minutes.
On the stroke of half-time, Marvin Morgan headed Ifil's looped cross back across goal which saw George Bentley stop Olumide Oluwatimilehin's strike, before Abrahams' placement was deflected wide.
11 minutes after the break, Gore dived to his left to palm away Lee Harding's 25-yard swerving strike. Three minutes on, Pamment could only guide Harvey Sparks' cross across the face of goal into the side-netting.
Kennedy and Roman Michael-Percil's one-two saw the former come inches away from guiding home inside the six-yard box on 67 minutes.
With the last meaningful play of proceedings, Kennedy found some success for the north Londoners two minutes on. Rifat sent Kennedy away down the left with a splendid outside-of-the-boot pass, who did the rest and confidently guided his chance into the far corner.
And despite a late flurry, Steve Clark's men were found wanting and an equaliser fizzled out.
