National Lottery players reported being unable to access the app and website after the group previously said it was investigating the error.
Both the website and the app seemed to be offline for many today – one day after the global IT failure caused widespread disruption at airports, businesses, the British health service and broadcasters.
Downdetector received thousands of reports of outages that began around 8:30pm on Friday night.
It is unclear whether the lottery’s problems are related to Friday’s outage.
In a post on X, the National Lottery stated: “We are aware that some players are having issues accessing our website and app.
“Sorry for the inconvenience, our team is currently investigating the issue to find out what happened.”
A spokesperson later said the website and app were working again, but many people continued to report problems for hours.

The global IT outage, which began on Friday morning, was caused by an update from global cybersecurity company Crowdstrike that took many Windows PCs offline and caused a “Blue Screen of Death” to appear on monitors.
The company founder later confirmed that the cause was a bug in the update and not a cyber attack, as some had feared.
George Kurtz said a fix had been rolled out but it would take “some time” for all systems to be restored. An industry expert warned it could take “weeks” to fully restore.
