Troubleshooting Blizzard Connection Issues
Check game-specific vs. platform-wide status
Blizzard's status page separates game servers from Battle.net services. If only one game is down while others work, it's a game-level issue. If Battle.net login itself is down, all games will fail together.
Patch and season launches cause predictable overloads
Blizzard games reliably experience login queue congestion within 24 hours of major patches, expansion launches, or new season starts. This is temporary — capacity typically normalizes within 2–6 hours as Blizzard scales servers.
Run the Battle.net Repair tool for persistent errors
Open the Battle.net app, click the game icon, go to Options → Scan and Repair. This fixes corrupt game files that can cause connection errors even when Blizzard servers are healthy.
DNS and firewall troubleshooting
If Blizzard's status page shows all green but you still can't connect: flush DNS (ipconfig /flushdns on Windows), switch to Google DNS (8.8.8.8), and ensure your firewall allows Battle.net and the game executables outbound on ports 1119 (TCP/UDP) and 3724 (TCP).
Authenticator issues during outages
The Blizzard Authenticator app uses time-based codes — if your phone's clock is off by more than 30 seconds, codes will fail. On Android: Settings → Date & Time → sync automatically. On iOS this is automatic. If codes keep failing during an outage, you can request an SMS code instead from the Battle.net login screen.

Frequently Asked Questions
Is Blizzard down right now?
To check if Blizzard is down, visit Blizzard's official status page at us.battle.net/status (US) or eu.battle.net/status (EU). You can also check Downdetector (downdetector.com/status/battle-net) for real-time user reports, or follow @BlizzardCS on X/Twitter for service announcements during incidents.
Why can't I log into Battle.net?
Battle.net login failures are usually caused by: (1) Server outage — check us.battle.net/status, (2) Wrong password or Battle.net tag — use 'Forgot Password' to reset, (3) Authenticator issues — remove and re-add the Authenticator app, (4) Account suspended — check your email for a Blizzard notification, (5) Regional maintenance — EU and US servers have separate maintenance windows. Try logging in via the Blizzard website instead of the desktop app.
Why is World of Warcraft not connecting?
WoW connection failures can stem from: (1) Realm maintenance — check the WoW Realm Status page at worldofwarcraft.com/en-us/game/status, (2) Blizzard server issues — check battle.net/status, (3) Your ISP routing issues — try a different DNS (8.8.8.8 or 1.1.1.1), (4) Windows Firewall or antivirus blocking WoW.exe, (5) Outdated WoW client — open Battle.net app and update. Running the Battle.net Repair tool also fixes many connection problems.
Why is Diablo 4 showing Error 300008?
Diablo 4 Error 300008 is a connection lost / login server error, almost always caused by a Blizzard server outage or maintenance window. Check us.battle.net/status to confirm. If servers are up, try: (1) Restart the Battle.net app and relaunch Diablo 4, (2) Flush DNS (ipconfig /flushdns on Windows), (3) Temporarily disable your VPN if you use one, (4) Check that TCP port 1119 and UDP 1119 are not blocked by your firewall.
What are Blizzard's major historical outages?
Blizzard's most notable outages include: the Wrath of the Lich King Classic launch in 2022, which caused multi-hour queue times and login failures for millions; the Diablo 4 Season of the Construct launch in January 2024, which overwhelmed login servers for the first 48 hours; and the ongoing DDoS attacks in 2023 that periodically disrupted all Blizzard game services simultaneously. Blizzard games consistently experience elevated issues within 24 hours of major patches or season launches.
🌐 Can't Access Blizzard?
If Blizzard is working for others but not for you, it might be an ISP or regional issue. A VPN can help bypass network-level blocks and routing problems.
Troubleshoot with a VPN
Connect from a different region to test if the issue is local to your network. Also protects your connection on public Wi-Fi.
