The website and app for BT Sport has gone down leaving football fans unable to watch three fourth-round FA Cup replay matches.
Those planning to watch the live games, including League Two club Cambridge United facing top flight club Manchester United, on computers through BT Sport’s online player or via mobile on the BT Sport app have been unable to watch the action.
BT have said it is aware of the problem and is trying to fix it.
Disappointed fans and BT Sport customers took to Twitter to complain
Dear @btsport if you don't have the infrastructure to run an app. Don't run one. Remind us what we pay for again?

The technical difficulties come as BT Sport gears up for bidding for another three years of rights to broadcast Premier League games against Sky, Al Jazeera and Discovery Communications.
BT Sport boasts more than one million customers since paying £738m to secure broadcast rights for 38 games every season in 2012.
