Hawks unfortunately went out of the County Cup at the last 16 stage.
The first half was an even affair, with both teams scoring twice, Jack Glenn netting a brace for the visitors.
Second half Hawks really should have won the game, with four gilt edged chances spurned.
Diss were made to pay for their profligacy in front of goal, when the ref awarded a penalty to the home side with two minutes to play, oh for VAR, not exactly a clear and obvious decision.
The home side scored the penalty, and that was the end of the road in this particular cup competition for the Hawks.
Full Time, 3-2 for Corinthians, and a tale of miss chances which should have seen Diss go through.
Next game, Fakenham at home 15th Dec 10-30 kickoff, back to league action.
