Goal-line technology provider Hawk-Eye has apologised to Huddersfield and the English Football League after the failure to award a goal to the Yorkshire side on Sunday.
The Terriers' Yuta Nakayama was denied an equaliser in the Sky Bet Championship match against Blackpool after the technology failed to send a signal to the watch of referee John Busby to alert him to the ball crossing the line.
The official and his assistants also failed to spot the ball had gone in.
The EFL issued a statement on Monday stating it was "incredibly frustrated" that the goal had not been awarded, and on Tuesday Hawk-Eye provided an explanation for the failure of the technology.
"Hawk-Eye can confirm that the ball was obscured from the goal-line technology tracking cameras as it moved over the line," the company’s statement read.
"The position of the players, the goal post and the goalkeeper impacted the cameras’ line of sight to the moving ball and as such, a decision could not be determined by the system."
Hawk-Eye said seven cameras are installed at each end of the pitch to track the ball, and a signal is sent to the match officials when two or more of the cameras can see it. It said the system had been deployed at more than 15,000 matches around the world since its first use in 2012.
"We would like to reassure the football community that this was an exceptional edge-case occurrence, and we will continue to review standard operating procedures for such occurrence with the EFL and PGMOL (Professional Game Match Officials Limited)," the statement continued.
"Hawk-Eye has spoken to both the EFL and Huddersfield Town FC and would like to apologise unreservedly to both parties."
Earlier this year, Hawk-Eye found itself the subject of unwanted scrutiny after a high-profile gaffe in the All-Ireland football semi-final between Galway and Derry.
A first-half point from Shane Walsh was ruled wide by the technology provider before being added to the Galway tally at the interval.
Concerns over the accuracy of Hawk-Eye meant the technology was dispensed with for the second half and wasn't deployed for the second semi-final between Dublin and Kerry.
