Diablo IV Season Launch Hit by Errors and Delays, Now Live
Sep-23-2026 PST
What Happened to Diablo IV's New Season?
Diablo IV's latest seasonal update did not get the start Blizzard planned. The season was supposed to kick off on the same day Diablo IV arrived on Switch 2 in the form of the Age of Hated Collection, an arrival GoNintendo described as announced just one week before its report. Instead of a smooth launch, players across the board ran into error codes and login issues when the update went live, according to GoNintendo [1].
Blizzard initially hoped it could get the situation under control without stepping back from the schedule. That changed as the problems persisted, and the studio officially confirmed a delay for the season. In its message, Blizzard thanked players for their patience while the team worked to resolve the issues [1].
When Did the Season Finally Go Live?
The delay turned out to be temporary. According to an update appended to GoNintendo's report, Blizzard has since fixed the issues and the season is now live. The original article promised that once a new launch date was shared, full details would follow, and the appended update confirmed the fix rather than announcing an extended wait [1].
For players who were locked out during the troubled rollout, the practical outcome is straightforward: the seasonal content is now accessible after the errors were resolved. The report does not specify the exact date or time the season went live, only that the issues were fixed and the season had launched [1].

What Does Season of Hell's Legacy Offer?
According to the report, the season — named Season of Hell's Legacy — offers a seasonal questline built around a living history of Diablo's past games, refreshed and recreated for Diablo IV. Players relive the past by encountering the memories of legendary heroes and notorious foes [1].
The questline also invites players to delve into the storied and troubled past of Sanctuary's long history. In short, the season is framed as a retrospective journey through the franchise's legacy rather than an entirely new storyline, with Diablo's earlier eras rebuilt inside the current game [1].

How Does the Switch 2 Release Fit In?
The season's troubled launch coincided with another milestone. As was announced just one week before the report, Diablo IV became available on Switch 2 in the form of the Age of Hated Collection. The game arrived on the same date the season was originally supposed to kick off, but the launch then ran into delays, per GoNintendo [1].
The report states the error codes and login issues affected players across the board. It does not break down whether Switch 2 players specifically were affected or attribute the problems to the platform's arrival.
What Does Diablo IV Include Beyond the Season?
The report also summarizes what Diablo IV offers as a whole. Blizzard describes it as an action-RPG with a campaign that can be played solo or with friends, a cast of memorable characters, and a gripping story set in a beautifully dark world [1].
Beyond the campaign, the game features an expansive end game: players battle iconic bosses for powerful loot, fight back the encroaching onslaught of Hell in Helltides, and master the Forge to create weapons and progress powerful characters. Cross-play and cross-progression are supported on all available platforms, according to the report [1].
What Did Blizzard Say About the Delay?
Blizzard's official communication, as relayed by the report, acknowledged the technical problems directly. The studio told players it appreciated their patience while working to resolve the issues, and indicated more time was needed to iron out the kinks before the season could properly proceed [1].
No detailed technical explanation of the error codes or login failures was included in the report. What is documented is the sequence: launch-day problems across the board, an official delay confirmation, and a subsequent fix that brought the season live [1].
How Does the Rival ARPG Landscape Look Right Now?
Diablo IV is not the only action-RPG with seasonal news this month. Last Epoch, developed by Eleventh Hour Games, is preparing its fifth season, "Rage of the Frostborn," scheduled for October 1, 2026, with additional details promised from September 21, as covered by ixbt.games [2].
The trailer highlighted the boss Morditas, God of Bloodshed; a new seasonal mechanic called "Rage of Morditas"; several additional skills; new item sets; and quality-of-life improvements such as a new interface for activities. Notably, that October 1 date and its content belong to Last Epoch, a separate game from a different studio — not to Diablo IV [2].
