Interesting endgame, I first looked at 56.Kg4 fxg3 57.Rh3, but both 57... Rc4+ as well as 57... Re1 draw.
'The shortest solution was 57.Rxf4!' - Yes, well, indeed. With a tablebase at hand the plan is not so difficult: rook to the e-file, knight to f4, king to g4 followed by Re6. But that requires good timing. In practice, the win is surprisingly hard, as was demonstrated. More so because black missed the draw.

White just played 82.Rd4-d7?. Now 82... g5! 83.h5 Ra2+ is a draw. Black will give checks on the a-file and when the king goes to far, black will play g4. The white rook can't interpose as black can win the pawn with either g3 or Kg5. If he seeks shelter at f7, the pawn keeps running; white has to stop it with the rook and the checks on the a-file can continue.
White erred again with 83.Kf1?, where after 83.K~3 g5 84.Ng4+ Kh5 85.Rh7+ the knight is defended. Black again had a draw with 84... g5. White should have answered 84... Ra2+ with 85.Kf3 instead of Kd3?.
Black missed his last chance with 88... Ra4?, where 88... g3! still would have saved the draw: 89.Ng4+ Kh7! 90.Rg5 Ra6 (or 90... Rf3) 91.Ne3 g2 92.Kb3 g1Q 93.Rxg1 Kh6 94.Rh1 Kg5! and 95... Rh6.
