Hereford's promotion charge was dealt a serious blow as the Bulls crashed to a 3-1 defeat at inconsistent Dagenham & Redbridge.
The Daggers had slipped down the Conference table in recent weeks after their excellent start to the campaign but they got back on track against a team they lost 9-0 to last season.
The hosts started brightly and Paul Bruce's 18th minute free-kick curled just wide.
Andy Tretton did well to cut out Mark Janney's cross on the half-hour but Hereford should have taken the lead eight minutes later when David Brown's 15-yard volley flew just wide.
Dagenham almost broke the deadlock early in the second period when Chris Moore wasted a great chance but Hereford broke quickly and Lee Mills was able to sidefoot home a Mark Robinson cross to put the visitors ahead.
The Daggers refused to lie down though and they equalised in the 57th minute when Bruce's corner caused chaos in the Hereford penalty area and Anwar Uddin's volley was nodded home at the far post by Craig Mackail-Smith.
John Still's side took the lead seven minutes later with a fortuitous goal as Chris Moore's cross-cum-shot deceived Gould at his near post before nestling in the back of the net.
Tim Cole then headed another Bruce corner narrowly wide but Dagenham sealed a fine victory in stoppage time when Mackail-Smith scored a fine individual goal.
