Step-by-Step Fix

1
Check Battle.net authentication status
Visit us.support.blizzard.com. Diablo IV is always-online and uses Battle.net auth — if auth is down, you cannot log in or play at all.
2
Restart Battle.net
Exit Battle.net from the system tray. Relaunch and attempt to log in. This refreshes the session token.
3
Clear Battle.net cache
Close Battle.net. Delete the "Cache" folder inside both %programdata%\Battle.net\ and %appdata%\Battle.net\. Relaunch and try again.
4
Disable Battle.net authenticator temporarily
If authenticator prompts are looping, visit account.battle.net → Security → remove the authenticator. Re-add it after successfully logging in.
5
Check your Battle.net account for bans or holds
Log into account.battle.net in your browser. Suspensions and account holds appear there and will prevent Diablo IV access.
6
Reinstall Battle.net Launcher
Uninstall Battle.net via Windows Settings → Apps. Download a fresh copy from battle.net. Diablo IV game files remain intact.
Is it server-side?
Check real-time player reports — if reports are spiking, it's on Blizzard Entertainment's end, not yours.

Frequently Asked Questions

Why can't I log into Diablo 4?

Diablo IV login requires Battle.net authentication. Login failures are caused by Blizzard auth being down (check us.support.blizzard.com), a stale session, or an account hold. Fully exit and relaunch Battle.net from the system tray.

Diablo 4 says "Game is temporarily unavailable" — what does that mean?

This message means Blizzard's game servers are undergoing maintenance or are overloaded. This is especially common during season launches. Check @BlizzardCS on Twitter for an estimated restoration time.

Can I play Diablo 4 offline?

No. Diablo IV requires a constant internet connection for all game modes, including solo play. If Blizzard's servers are down, you cannot play. There is no offline mode.
