Liverpool v Stoke was the first game of the Premier League season
Some BT Sport customers have complained of problems with the broadcaster's mobile app as it aired its first live Premier League match.
Hundreds tweeted about problems, some saying they got the message: "Sorry we are having some temporary technical issues, please try again later."
BT Sport said the issues had affected "a minority" of customers who tried to log in once the game had started.
It said it responded quickly so most customers could watch the second half.
Telecoms giant BT launched its own UK sports channels earlier this month.
It has spent £738m over three years for the rights to 38 live Premier League matches a season, while Sky has paid £2.3bn for 116 matches a season.
The issues arose during the Liverpool v Stoke City, the first game of the Premier League season which kicked off at 12:45 BST and ended with a 1-0 victory for the home side.
'Intermittent issue'One Twitter user, Andrew Muirhead, posted: "BT sport app thanks for cutting out on the first game of the season!"
Another, James Bufton, said: "Unfortunately due to the failings of the BT Sport app, I couldn't witness the first goal of the PL season."
Others complained the app would only work on a wi-fi connection.
The official BT Sport Twitter account replied to some individual users, suggesting they log out and log back in again.
It tweeted: "Sorry, some customers have seen an intermittent issue with the BT Sport App. We are working to resolve this, apologies to everyone affected."
A BT spokeswoman said: "Those customers who logged in before the game have experienced no issues but a minority of customers who tried to login once the game had started may have seen an intermittent issue and an error message.
"Our team responded quickly and were able to make a difference so most of the customers who were experiencing problems were able to enjoy the remainder of the second half."
The spokeswoman said the new broadcaster had been following feedback closely on social media for its first Premier League game and was "really pleased so many customers have enjoyed the coverage".
