The session, which was scheduled to begin at 11:00 BST, saw many users stuck at the game's main menu and repeatedly failing to authenticate with online services.
FromSoftware's support team acknowledged the outage and confirmed the closure of today's session.
In a social-media update, the developer apologized to players affected by the disruption, confirmed that the first test would not continue, and said it would keep working to improve server stability and publish updated test schedules at a later date.
This statement makes clear that the company is treating the outage as a technical issue requiring further work before resuming network testing.
Players and journalists reported the inability to reach online services immediately after the test opened.
FromSoftware had indicated it was aware of connection problems and was attempting to resolve them, but the developer ultimately closed the session when fixes could not be applied in time.
This is not the first time an early FromSoftware network test has experienced difficulties.
Early sessions for previous network tests drew similar issues, and outlets such as IGN reported comparable server problems during past trials.
Network tests are intended to expose and resolve these kinds of issues before full launch, and FromSoftware's statement commits to further improvements and future scheduling updates.
The Duskbloods is the latest project from FromSoftware, a studio known for its influential work in the action-RPG space — including the critically acclaimed Elden Ring and earlier Soulsborne titles.
FromSoftware's releases have historically appeared across platforms including PlayStation, Xbox and PC; several of the studio's titles or remasters have also been made available on Nintendo Switch and digital storefronts such as the Nintendo eShop.
At this time, FromSoftware has not provided a new date for a replacement session.
The studio's posted message indicates it will announce additional network-test schedules once server improvements are in place.
Readers hoping to participate in future tests should monitor FromSoftware's official channels for confirmed times and further technical guidance.
