• A fast, practical checklist to get PiVPN working again
• How to diagnose both server-side and client-side problems
• Protocol-specific tips for OpenVPN and WireGuard
• Real-world scenarios with fixes
• A thorough FAQ to cover common questions and edge cases

1. Quick-start checklist: can you reach the basics again?

• Confirm the PiVPN service is running
  • For OpenVPN: sudo systemctl status openvpn@server
  • For WireGuard: sudo systemctl status wg-quick@wg0
  • If it’s not active, restart it: sudo systemctl restart openvpn@server or sudo systemctl restart wg-quick@wg0
• Check the server’s listening ports
  • OpenVPN typically uses UDP 1194 sometimes TCP 443 in some setups
  • WireGuard typically uses UDP 51820 by default
• Use a local test from the Pi: sudo ss -tulpen | grep -E ‘1194|51820|443’
• Look at the system logs for clues
  • OpenVPN: sudo journalctl -u openvpn@server -n 50
  • WireGuard: sudo journalctl -u wg-quick@wg0 -n 50
• Verify client profiles exist and match the server
  • PiVPN: pivpn -a -p to add a new client if needed
  • Check the server config paths depends on protocol
• Test basic connectivity from the Pi itself
  • For OpenVPN: can you reach an internal resource via the VPN network? Try pinging an internal host
  • For WireGuard: sudo wg show to verify peer status
• Confirm router port forwarding or firewall rules aren’t the blocker
  • UDP ports 1194 OpenVPN or 51820 WireGuard must be open to the internet if you’re remote
• Make sure the Pi’s clock is accurate
  • Time drift can cause TLS certificates to fail handshake
  • sudo timedatectl

2. Step-by-step fast fixes start here and then drill down
   A. Restart and reset traps

• Restart the VPN services and the networking stack
  • OpenVPN: sudo systemctl restart openvpn@server
  • WireGuard: sudo systemctl restart wg-quick@wg0
• If you keep seeing a “TLS handshake failed” message, restart the Pi soft reboot and re-test
  • sudo reboot
    B. Validate server configuration and scripts
• Confirm the pivpn installation isn’t corrupted
  • Run: pivpn -v to see the version. if you suspect corruption, back up, then reinstall
• Check setupVars.conf for OpenVPN or WireGuard configuration differences
  • OpenVPN: sudo cat /etc/pivpn/multi.conf or /etc/openvpn/server.conf
  • WireGuard: sudo cat /etc/wireguard/wg0.conf
• Ensure DNS and domain settings are sane
  • If you’re using a domain name to reach the VPN, verify DNS resolution from clients
    C. Rebuild or reissue client profiles
• If a specific client can’t connect, recreate its profile
  • pivpn -a -n ClientName -p -secret or appropriate flag
  • Transfer the new .ovpn or .conf to the client and test again
• Verify the client config matches the server’s configuration crypto, keys, endpoints
  D. Check firewall rules on the Raspberry Pi
• ufw status or sudo iptables -L
• If needed, allow the VPN port:
  • OpenVPN: sudo ufw allow 1194/udp
  • WireGuard: sudo ufw allow 51820/udp
• Ensure NAT is enabled if you’re routing traffic out of the VPN
  • See typical iptables masquerade rule: sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
  • Save rules if you’re using iptables-persistent or equivalent
    E. Confirm port forwarding and your router setup
• If you’re behind CGNAT or a residential router, you’ll need an external port forward to the Pi
• Use a port-checker from an external network to confirm the port is reachable
• If you’re behind a corporate or university network, rules may block VPN traffic. test on a home network to confirm
  F. Inspect client-side issues
• Ensure the client device supports the chosen protocol and has the correct certs/keys
• On mobile devices, verify the VPN profile hasn’t expired
• If a corporate MDM or security profile blocks VPN, check device management policies
  G. Update and patch
• Keep PiVPN and the OS up-to-date
  • sudo apt update && sudo apt upgrade -y
• If you’re using the PiVPN script, re-run the installer to refresh configs: curl -L https://install.pivpn.io | bash
• If you suspect a bug, check GitHub issues or community forums for your latest version notes
  H. Check for IP route and DNS leakage
• With VPN connected, test for DNS leaks using dnsleaktest or dnsperf
• Confirm the VPN is routing all traffic, not just VPN traffic
• If you’re using split-tunnel, confirm which traffic is allowed through the VPN
  I. Validate certificate expirations and keys
• Expired certificates will block SSL/TLS handshakes
• Check expiry with openssl: openssl x509 -in /path/to/cert.pem -noout -dates
• If needed, reissue keys and re-distribute credentials to clients
  J. Consider reinstalling as a last resort
• If everything seems broken beyond quick fixes, a clean reinstall of PiVPN on a fresh image often saves time
• Back up your configs first e.g., /etc/wireguard, /etc/openvpn/server.conf, and client profiles

3. Protocol-specific tips: OpenVPN vs WireGuard
   OpenVPN

• Pros: Mature, highly compatible, robust across networks
• Cons: May be slower on older hardware, more overhead
• Quick wins:
  • Ensure UDP is used when possible some networks block TCP easily
  • Check for mismatched cipher settings between server and client
  • Confirm the server’s certificate bundle is valid and not expired
    WireGuard
• Pros: Very fast, lean, simpler configuration
• Cons: Fewer legacy options, some older clients may need updates
  • Confirm the WG0 interface is up and peers match on server and client
  • Ensure the public key on the server is the same as the client’s public key in the config
  • Verify MTU is appropriate for your network try 1420 as a starting point

4. Real-world troubleshooting scenarios
   Scenario 1: Client can connect but cannot reach the internet

• Likely cause: No NAT/MASQUERADE rule on the Pi, or firewall blocks outbound traffic
• Fix: Add an iptables MASQUERADE rule and ensure IP forwarding is enabled:
  • sudo sh -c “echo 1 > /proc/sys/net/ipv4/ip_forward”
  • sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
  • Make it persistent with your distro’s method iptables-persistent or nftables
    Scenario 2: Client reports TLS handshake failed
• Likely cause: Certificate mismatch or expired CA/certs
• Fix: Reissue client certificates and confirm the CA cert on the server matches the client
  Scenario 3: VPN tunnel builds but drops after a few seconds
• Likely cause: MTU issues or DNS resolution problems
• Fix: Adjust MTU in the client profile e.g., 1420, test with different DNS servers on the client
  Scenario 4: OpenVPN client cannot connect from outside your network, but works on local LAN
• Likely cause: Port forwarding not set up or ISP blocks VPN ports
• Fix: Double-check port forwarding rules, test with a port checker from outside, consider changing to a common port like 443 as a workaround if your ISP blocks 1194

5. Performance and security best practices

• Rotate keys and reissue client profiles periodically
• Keep firmware and OS up-to-date to patch security flaws
• Use strong authentication and encryption settings appropriate to your hardware
• Regularly review your firewall rules to prevent leaks
• Consider a backup VPN plan or failover in case the primary VPN server goes down
• Limit VPN access to only the devices you trust by using client-specific profiles and revoking unused ones
• Monitor VPN activity and set up simple alerting on unexpected spikes in traffic or failed handshakes
