- Release and renew your IP and flush your DNS to resolve any network conflicts.
- Run the Blizzard Battle.net Desktop App in Administrator Mode to address many installation, patching, networking, and start-up errors.
- Disable any proxies that may interfere with the login module.
- Try creating a new administrator account to resolve permissions issues.
- If you're using a VPN, try removing it.
- Run a security scan to remove any viruses or malware infections.
