World Rugby have admitted that a mistake was made by the television match official (TMO) in Wales' 12-6 defeat by England.
TMO Glenn Newman ruled Anthony Watson had beaten Gareth Anscombe to the ball, with Wales coach Warren Gatland describing it as "a terrible mistake."
Rob Howley says World Rugby's Alain Rolland has confirmed the error.
"It was good to have dialogue with World Rugby... they confirmed the TMO made a mistake," Howley confirmed.
"That dialogue happens continually throughout international periods," he continued.
"That phone call took place yesterday and Alain Rolland confirmed on behalf of World Rugby that it was a mistake.
"I haven't spoken to any of the match officials. It's happened, it's disappointing that happens in professional sport. But we focus on the next two weeks and getting ready for Ireland."
In a statement issued to BBC Sport Wales, World Rugby confirmed Howley's comments.
"World Rugby has clarified to the Wales team management as part of the usual review process with teams that the TMO made an error in the application of law during the England versus Wales match at Twickenham," they said.
"In accordance with law 21.1 b Wales should have been awarded a try as the Wales player grounded the ball."
England coach Eddie Jones compared the incident to a batsman being wrongly given out in a cricket match.
"The decision is made, that's the game and I'm sure Wales are upset about it and I can understand why, but the game is gone," he said.
Injury boosts ahead of Ireland
However, Howley did have good news for Wales in terms of injuries ahead of the next match with Ireland.
Leigh Halfpenny, Dan Biggar and Taulupe Faletau are all expected to return to full training by the end of the week.
Halfpenny will take some part in training in "the next few days" after a foot infection forced him to withdraw from facing England last weekend.
Biggar is expected to take a full part in training by the weekend and Wales hope Faletau will have some game time with his club side Bath.
Howley also confirmed Saracens' Liam Williams came through his return match with without problem but wing Alex Cuthbert is out of the squad because of a knee injury.
However, Gloucester say that back-rower Ross Moriarty will miss Saturday's Premiership match at Worcester, because of a shoulder injury. However, they expect Moriarty to be available to face Ireland.
