Bala Town 2-1 Differdange 03
Omar Er Rafik's added-time goal broke Bala Town hearts in the Europa League first qualifying round.
Colin Caton's side led 2-0 after 82 minutes thanks to second-half strikes by Conall Murtagh and Ian Sheridan.
That would have put the north Wales club into the next round, with a game scheduled at Cardiff City Stadium against Turkey's Trabzonspor.
But Er Rafik, on target in the Luxembourg team's 3-1 first-leg win, scored to seal a 4-3 aggregate victory.
