Network and DNS
- Check basic connectivity:
- Open a browser and confirm you can reach the internet. If not, troubleshoot your local network first.
- DNS configuration:
- Use automatic DNS or switch to a trusted DNS e.g., 1.1.1.1, 8.8.8.8 temporarily to see if resolution improves.
- Disable VPN-related proxies:
- If you’re using a proxy, disable it in Windows settings and in the GlobalProtect client if applicable.
- Flush DNS:
- Open Command Prompt as administrator and run: ipconfig /flushdns
- Check split tunneling:
- Some networks require all traffic through VPN; confirm whether split tunneling is enabled or disabled as required by your IT policy.
- Reset network adapters:
- In Network & Internet settings, reset the adapter or disable/enable the virtual adapters created by GlobalProtect.
Certificate and authentication
- Validate certificates:
- Ensure the VPN server certificate is trusted on your device. If your organization uses a private CA, the root or intermediate certificates must be installed.
- Check certificate validity:
- Look for expiration dates and revocation status.
- Time and date accuracy:
- Make sure your system clock is synchronized with an accurate time source.
- Re-authenticate:
- If your organization uses MFA, ensure your MFA device is accessible and not expired.
- Check for certificate pinning or policy changes:
- IT may have updated certificate requirements; confirm with your admin if you see certificate errors.
- Import intermediate certificates:
- Sometimes only the root CA is installed; you may need to install the intermediate certificate chain.
Firewall and security software
- Temporarily disable Windows Defender Firewall:
- Turn off temporarily to test if it’s blocking VPN traffic. Re-enable after testing.
- Check third-party antivirus/firewall:
- Some security suites block VPN tunnels; add GlobalProtect to allowlists.
- Verify Windows security policies:
- Ensure no group policy settings block VPN connections or require specific tunneling modes.
Gateway and server settings
- Verify portal URL and gateway name:
- A wrong URL or gateway can prevent login or connection.
- Check gateway reachability:
- Ping or traceroute to the gateway to see if it’s reachable from your network.
- Confirm portal certificate matching:
- Ensure the portal URL matches the certificate. Mismatched certificates cause errors.
- Check for maintenance outages:
- IT may be performing maintenance; confirm status with your network admin.

- If you have access to another Windows 11 device that connects fine, compare settings and network conditions.
- Consider alternative gateways:
- Some organizations publish multiple gateway addresses for load balancing and failover; verify you’re using the correct one.
