The Dublin portal has been closed and will reopen later this week after a solution of "blurring" to address lewd behaviour in front of the installation has been deemed as unsatisfactory.
The livestream art project allows people in Dublin and New York to connect via a live video feed.
The Dublin portal is located between O'Connell Street and North Earl Street in the city centre, while the New York portal is located on the Flatiron South Public Plaza at Broadway, Fifth Avenue, and 23rd Street.
However, inappropriate behaviour "by a small minority of people" led Dublin City Council (DCC) and the team behind the portal to find "technical solutions" to address it.
The preferred solution, which would have involved blurring any images held up to the camera, was not satisfactory, it said.
DCC said the team behind the portal, portals.org, was now investigating other "technical solutions".
As a result, the portal was switched off at 10pm and will be switched back on later this week.
Nicolas Klaus, head of partnerships at portals.org, said the team are adjusting the portal "on the go".
Portal closes for a time as 'blurring' unsatisfactory
