Football fans who attempted to watch the climax to the Barclays Premier League season on Sky Go and NOW TV on Sunday were left disappointed following technical problems.
Network congestion meant consumers - including those who paid £9.99 for a NOW TV Sky Sports Day Pass - were unable to watch the season finale online.
As the final 2013-14 games were kicking off live on Sky Sports, video streams stopped and Sky viewers received the message: 'Oops, something went wrong'.
Sky issued an apology for the outage via its NOW TV community page.
"We'd like to apologise again for this afternoon's issues. We're working as hard as we can to get things running as soon as possible," the service provider stated.
"We'll be contacting all sports pass customers automatically to provide a refund or a replacement pass. You don't need to do anything to make this happen."
This is not the first time Sky has struggled to cope with demand for online access to popular broadcasts.
In early April, the first episode of season four of 'Game of Thrones' was disrupted, with some viewers receiving error messages or suffering slow loading times.
