Forest Green finished fifth in the Conference in 2014–15, qualifying for the promotion play-offs; they went on to lose 3–0 on aggregate to Bristol Rovers in the semi-finals. The following season saw them finish as runners-up in the renamed National League, their highest-ever league position; in the subsequent play-offs they defeated Dover Athletic 2–1 in the semi-finals, before losing 3–1 to Grimsby Town in the final at Wembley. A third consecutive play-off campaign was secured with a third-place finish in 2016–17. After beating Dagenham & Redbridge 3–1 in the semi-finals, the club defeated Tranmere Rovers by the same scoreline in the final at Wembley, earning promotion to League Two. This made Nailsworth the smallest town ever to host a Football League club.
