What network configuration issues, beyond proxy settings, can trigger error 12007?

Beyond proxy settings, other network configuration issues that can trigger error 12007 include incorrect DNS server configurations (preventing hostname resolution), an invalid or conflicting IP address setup, a malfunctioning network gateway (router), or even local network congestion. Ensuring your network adapter drivers are up to date and your Wi-Fi or Ethernet connection is stable and properly configured can also prevent this error. Running Windows Network Troubleshooter can help identify some of these issues.
