SO Town will be kicking their heels when Histon, Hinckley and Halifax go hunting a place in the FA Cup third round next month.
And they've got only themselves to blame.
Suicidal defending cost Town dearly against League I's basement club and 1,400 travelling fans were voting with their feet long before the end.
Mugged by an Ashley Williams header and two strikes from Warren Feeney - the second of which, crucially, came only seconds before half time - Town sank for the second successive season at the first time of asking.
It looked like their run without an FA Cup goal would stretch to a fourth year, too, until Pawel Abbott nipped through in stoppage time at the end to bag his 13th of the season.
That was too little too late, however, to make up for the disappointment which had gone before against a Stockport side earning only their second Edgeley win of the season.
The first half was a disaster with two goals conceded scrappily from corners and the other on the break when Sammy McIlroy's side had three in attack to Town's two covering men.
Loan keeper Paul Rachubka, who had conceded three only once previously in Town colours (against Mansfield at home last season), must have wondered what was happening.
The front two of Abbott and Junior Mendes did nowhere near enough, the midfield three were stretched in their defensive duties and the back line were all over the place.
No wonder they were roundly booed off at the break.
Even then, if Town could have got themselves back into the game with a goal it was quite conceivable Stockport would have panicked and become more vulnerable, but it wasn't to be.
Despite dominating possession in the second half - when Rachubka didn't have a save to make - and attacking almost at will to the edge of the box, Town weren't decisive enough in the area, missing the threat the injured Andy Booth might have offered.
Keeper James Spencer was lucky, in the 61st minute, when Mendes' low shot was blocked on the line by John Hardiker, but Spencer was well placed to save a Danny Schofield shot, an Andy Holdsworth free-kick and a stinger from sub Lee Fowler with Stockport under a fair amount of pressure.
Shots by Abbott (just after half time) and Worthington were only narrowly off target, too, but the damage had been done in that shocking first period.
Stockport were ahead after only seven minutes when Nathan Clarke momentarily lost centre-back Williams at a Danny Griffin corner and a back-post header left Jackson's men with a mountain to climb.
That mountain became higher on 19 minutes when Chris Williams, sprinting down the left, played a lovely diagonal ball to leave Feeney one-on-one and he supplied a low right-foot finish to grace even the final of this wonderfully exciting competition.
Stockport were finding far too much time and space at that stage, but Town could feel rightly aggrieved when a potential lifeline was ripped from their hands in the 39th minute.
It seemed a fairly straightforward decision when Worthington had his feet taken from under him from behind by Hardiker in the box, but referee Graham Laws was having none of it and Stockport, who had the suspended Efe Sodje to contend with in their League defeat to Town, took full advantage.
Play was already into added time at the break when Williams' corner was missed by Schofield at the near post, Rachubka could only parry as he was startled by the mistake and Feeney was gleefully on hand to deliver the third and killer blow.
While Town's second-half showing was improved, and Lloyd deserves credit for his battling display over the whole 90 minutes, it is hard to see them making a sustained challenge for the play-offs this season until they can stop conceding goals.
They were stretched by loan man Andy Smith - a lookalike of his namesake Alan - but the goals were gifted all too easily.
And four clean sheets (one of them against Morecambe in the LDV Vans Trophy) from 21 senior matches this season just isn't good enough; something Jacko knows only too well.
