What People Experience When Proton VPN Disconnects
- You may see sudden drop-offs with your IP changing, or the app showing “Disconnected” followed by “Connecting…”
- In some cases, DNS leaks or IPv6 leaks trigger disconnects or safety warnings
- On mobile networks, signal strength and carrier restrictions can cause frequent handoffs
- On desktops, antivirus/firewall rules can block VPN tunnels or force re-authentication
Key Reasons Proton VPN Might Disappear Your Connection
- Server-side issues: some servers have higher latency or instability than others
- Protocol selection: certain protocols may be blocked or throttled by networks
- Kill Switch settings: overly aggressive Kill Switch behavior can cut traffic if the VPN momentarily drops
- IP leaks and DNS: misconfigurations can cause the VPN to drop to a non-protected state
- Local network problems: router settings, double NAT, or ISP throttling
- App or OS bugs: outdated apps or OS versions can mis-handle VPN tunnels
- Third-party software: firewall, antivirus, or other VPNs can conflict
Step-by-Step Troubleshooting: Quick Wins 5-15 minutes
- Step 1: Check server status and switch servers
- Open Proton VPN and check the server list
- Connect to a nearby server or a different country and see if the issue persists
- If you’re using a specialty server like P2P or Secure Core, try a standard server first
- Step 2: Change protocol and test stability
- If you’re on OpenVPN UDP, try TCP; or switch to WireGuard if available
- Some networks block certain protocols; changing can restore stability
- After switching, test streaming, browsing, and application usage
- Step 3: Review Kill Switch and DNS settings
- Temporarily disable Kill Switch to test if the disconnects stop
- Enable only if you see leaks, but keep it enabled once you confirm stability
- Use Proton VPN’s DNS or a trusted DNS e.g., Cloudflare 1.1.1.1 or Google 8.8.8.8 and test
- Step 4: Reboot and re-test
- Restart the Proton VPN app, then reboot your device
- If you’re on a router, power cycle the router as well
- Step 5: Update software and firmware
- Ensure Proton VPN app is at the latest version
- Update your device OS to the latest security patch
- If you’re on router-based VPN, update router firmware
- Step 6: Check for conflicts with other software
- Temporarily disable antivirus/firewall or enterprise security tools to test
- If VPN works with them off, add an exception for Proton VPN
- Step 7: IPv6 and DNS considerations
- Disable IPv6 in the VPN client if you’re experiencing leaks or instability
- If IPv6 is enabled on your device, you may see conflicts if only IPv4 is routed through VPN

Router and Network Environment
- Double NAT and router settings can cause VPN disconnects
- If you’re behind double NAT, consider placing the router in bridge mode or enabling passthrough for VPN
- QoS and bandwidth limitations
- Disable QoS rules that might throttle VPN traffic
- Ensure your ISP isn’t actively blocking or shaping VPN traffic; contact support if you suspect throttling
- DNS and IPv6 considerations for your network
- Disable IPv6 on the router if you’re not using IPv6 through VPN
- Set the router to use a reliable DNS 8.8.8.8 / 1.1.1.1 and test again
- Public Wi-Fi caveats
- Public networks often require re-authentication; ensure you remain signed in and the VPN has permission to route traffic
Proton VPN Settings That Improve Stability
- Kill Switch configuration
- Select a balanced Kill Switch mode disconnects when VPN drops and test stability
