Fix: VPN Won't Connect (Basic Checklist)

1. Check your internet: Make sure you can browse the web without the VPN. If your internet is down, the VPN cannot connect either.
2. Restart the app: Close Shieldeum completely and reopen it. This resolves most temporary glitches.
3. Try a different server: The server you selected might be temporarily unavailable. Pick another location.
4. Switch protocols: Go to Settings and try a different protocol. If WireGuard is not working, try OpenVPN UDP or TCP.
5. Update the app: Make sure you are running the latest version of Shieldeum.

• Firewall or antivirus: Some security software blocks VPN connections. Try temporarily disabling your firewall to test, then add Shieldeum as an exception.
• Network restrictions: Some networks (corporate, school, public) actively block VPN traffic. Try Stealth mode, which disguises your VPN connection as regular HTTPS traffic.
• DNS issues: Flush your DNS cache. On Windows, run ipconfig /flushdns in Command Prompt. On macOS, run sudo dscacheutil -flushcache in Terminal.
• Reinstall: If nothing else works, uninstall Shieldeum, restart your device, and reinstall from scratch.

If none of these steps resolve the issue, contact our support team with the following information: your operating system, the protocol you tried, the server location, and any error messages you see. This helps us diagnose the problem faster.
