Diablo 4 and Battlenet games suffer Blizzard DDoS attack

A Blizzard DDoS attack appears to have brought down Diablo 4 and potentially the Overwatch 2 shop, as the developer works to rectify the issue.

June 25, 2023: According to Blizzard the DDoS attack on Battle.net has been resolved, so it’s recommended that you attempt to log in again.

Diablo 4‘s servers and the Overwatch 2 shop are down as a Battle.net Blizzard DDoS attack appears to be ongoing, impacting access to different multiplayer games. So if you can’t access Blizzard’s newest game and keep seeing a Diablo 4 unable to find a valid license message, that’ll be why.

If you’re seeing messages in Diablo 4 like “unable to find a valid license,” that might very well be because of an ongoing Blizzard DDoS attack.  It also looks like the Overwatch 2 shop is down as well due to sporadic reports, although it’s currently unclear if that’s for the same reason.

“We’re currently investigating an issue affecting our authentication servers, which may result in failed or slow login attempts,” the Blizzard customer support account for The Americas said earlier today, before adding “We continue to actively monitor an ongoing DDOS attack which is affecting latency/connections to our games [on Battle.net].”

The actual Battle.net launcher provides some more context, as a drop-down message reads “We are currently experiencing a DDoS attack, which may result in high latency and disconnections for some players. We are actively working to mitigate this issue.”

As of publication, it’s unclear when Battle.net will be up to full force again, but we at PCGamesN currently get an error message when looking at Diablo 4 on the launcher. The Diablo 4 servers have been down recently which may very well be related, while other players have been reporting a Diablo 4 error code 315306 message as well.

We’ll keep an eye out for any updates and let you know if anything changes, but for now, you might struggle to play games on Battle.net like Diablo 4, Overwatch 2, Call of Duty Modern Warfare 2, and Warzone 2.
