The Game of Thrones premiere killed off HBO Go.

HBO’s online streaming service had problems during the season 4 premiere of the hit fantasy service, with many receiving a “fatal error” message.

“HBO Go did experience issues due to overwhelming demand around the premiere of Game of Thrones,” the network said in a statement. “The service has returned to several platforms and we are working hard towards full recovery, which we expect soon.”

The premium cable service’s official Twitter account acknowledged the problem and urged patience:

HBO Go previously had trouble during the True Detective finale last month.
