Is Heroes of the Storm Down? Live status & outage reports

Service info and troubleshooting

Game Won't Launch at All

If the Battle.net launcher opens fine but Heroes of the Storm refuses to start, the first thing to check is whether your system meets the minimum requirements. After that, try deleting the Battle.net cache folder — it's tucked away in %​ProgramData%/​Battle.​net/​Agent. Corrupt cache files are a surprisingly common culprit. Also make sure your GPU drivers are up to date and that the game files aren't blocked by your antivirus.

High Ping and Match Lag

Latency spikes during matches usually come from one of a few places:

• Background apps hogging bandwidth — close anything that streams, syncs, or downloads
• Wi-Fi instability — switch to a wired connection if you can
• Router QoS settings — prioritize gaming traffic in your router's admin panel
• ISP routing issues — run a traceroute to the game servers to spot where packets drop

Login Errors and Authentication Failures

Error codes like BLZBNTBNA00000005 or a blank login screen usually mean either the Battle.net authentication servers are having a moment, or your local credentials cache is broken. Clear the Battle.net app cache, log out completely, and try again. If the error persists, check whether your system clock is set correctly — mismatched time causes SSL handshake failures that look like login bugs.

Game Files Won't Scan or Repair

When the 'Scan and Repair' option loops endlessly or fails partway through, the issue is often a permissions problem. Right-click the Battle.net launcher and run it as administrator, then try the scan again. If that doesn't help, temporarily disable your antivirus — some real-time protection tools lock game files mid-scan and corrupt the process.

Matchmaking Gets Stuck

• Check that your firewall allows outbound UDP on ports 1119 and 3724
• Flush your DNS cache with ipconfig /flushdns
• Restart the Battle.net app fully, not just minimize it
• If the queue never pops, the region servers may be under load — try switching to a different game region temporarily
