Section: Understanding why Proton VPN might block internet access
There are several common culprits when Proton VPN gives you a no-internet message:
- Network or router issues: your base connection could be down or unstable
- DNS problems: DNS requests leak outside the VPN or fail, preventing page loads
- Protocol or server problems: the chosen protocol/server combination isn’t working in your region
- Kill Switch or firewall interference: your device blocks VPN traffic when the app is not connected
- IPv6 leaks or misconfigurations: IPv6 traffic bypasses the VPN, causing leaks or disconnects
- Software conflicts: antivirus, firewall, or other VPNs/services on the device can conflict
- Outdated app or firmware: older versions may have bugs or incompatibilities
- Geographic or policy blocks: some networks like campus or corporate networks block VPN traffic
Data-backed context
- WireGuard is widely recommended for speed and stability, but some networks may block certain ports; OpenVPN remains a solid fallback.
- DNS leaks are a frequent cause of no-internet experiences; ensuring IPv6 is disabled and DNS requests go through the VPN helps.
- Kill Switch is essential for preventing data exposure if VPN drops; if it’s misconfigured, it can cause loss of connectivity.
Section: Quick platform-agnostic fixes try these first
- Restart everything: reboot the device and relaunch Proton VPN
- Switch servers: pick a different country and near location for better latency
- Change protocol: switch to WireGuard; if issues persist, try OpenVPN UDP/TCP
- Disable IPv6: turn off IPv6 in Proton VPN settings and system network settings
- Check Kill Switch: enable it if you haven’t, and test with and without it
- Verify DNS: ensure the VPN handles DNS Most VPNs offer a DNS feature; enable it
- Firewall/antivirus check: temporarily disable to test. If VPN works, create an exception
- Check network type: if you’re on a public Wi-Fi, switch to a trusted network or use a hotspot
- Reinstall if needed: uninstall, reboot, and reinstall the Proton VPN app
Platform-specific fixes
Windows
- Ensure Proton VPN runs with admin rights
- Disable IPv6 in Network Connections properties
- In Windows Firewall, allow Proton VPN and its executables
- Flush DNS: open Command Prompt as admin and run ipconfig /flushdns
- Change DNS to a public resolver for before/after testing e.g., 8.8.8.8, 1.1.1.1
- Check for conflicting VPNs or network-sense apps and disable them

- Use a different network tested with the same device to rule out local network issues
- Check for IPv6 traffic leaks: disable IPv6 everywhere possible
- Inspect firewall rules: ensure VPN traffic isn’t blocked by port or app rules
- Review VPN logs: look for error codes related to authentication, handshake, or protocol mismatch
- Test with a clean profile or guest session to isolate extensions or add-ons
- Look for system updates: OS updates can affect VPN performance, security, and compatibility
- Consider hardware constraints: older devices may struggle with certain VPN protocols
