Common reasons ProtonVPN won’t open
- The app is outdated or corrupted
- Your device’s firewall or security software blocks it
- Network issues or DNS problems prevent startup
- ProtonVPN servers or service are temporarily down
- Conflicting VPN profiles or other VPN software installed
- OS-specific issues, like permission prompts or sandboxing
Understanding the problem helps you pick the fastest fix. If you’re seeing a specific error message, note it down and search for that code in ProtonVPN’s knowledge base for a targeted solution.
Quick-start troubleshooting 5–10 minutes
1 Restart the app and device
- Close ProtonVPN completely ensure it’s not running in the background.
- Reopen the app and try to connect.
- If it still won’t open, reboot your device and retry.
2 Check for updates
- Update ProtonVPN to the latest version on your device’s app store or download the newest installer from ProtonVPN’s site.
- After updating, try launching again.
3 Verify account status
- Confirm your ProtonVPN subscription is active and hasn’t expired.
- Sign out and sign back in to refresh your session.
4 Check your internet connection
- Make sure you have a stable internet connection without VPN requirements to reach ProtonVPN servers.
- Disable other VPNs or firewall rules temporarily to see if ProtonVPN launches.
5 Disable conflicting software
- Some security software antivirus, firewall, or parental controls can block VPN apps.
- Temporarily disable conflicting apps and try ProtonVPN again.
Platform-specific fixes
Windows
- Run as Administrator: Right-click the ProtonVPN icon and choose “Run as administrator.”
- Network reset: Open Command Prompt as admin and run:
- netsh winsock reset
- netsh int ip reset
- ipconfig /release && ipconfig /renew
- Check Windows Firewall: Ensure ProtonVPN is allowed through the firewall.
macOS
- Check Gatekeeper settings: System Preferences > Security & Privacy > General, allow ProtonVPN.
- Reinstall with a clean slate: Remove ProtonVPN, restart, then install the latest version.
- Privacy permissions: Ensure ProtonVPN has network access in System Preferences > Security & Privacy > Privacy.
Linux
- Use the official client or verify OpenVPN/WireGuard dependencies.
- Check service status: systemctl status protonvpn, journalctl -u protonvpn
- Confirm network permissions are not blocked by firewall ufw/iptables.
iOS
- Force close the app and reopen.
- Check iOS VPN & Device Management settings to ensure ProtonVPN is allowed.
- Update iOS to the latest version and reinstall ProtonVPN if needed.
Android
- Clear cache and data for the ProtonVPN app.
- Check device admin settings for any VPN restrictions.
- Ensure cellular data or Wi‑Fi network allows VPN traffic and isn’t blocking the app.
Network and DNS fixes to fix “not opening” issues
6 Change DNS settings
- Use Google DNS 8.8.8.8 and 8.8.4.4 or Cloudflare DNS 1.1.1.1.
- On Windows: Control Panel > Network and Sharing Center > Change adapter settings > > Properties > Internet Protocol Version 4 TCP/IPv4 > Use the following DNS server addresses.
- On macOS: System Preferences > Network > Advanced > DNS > add 8.8.8.8 and 8.8.4.4.
7 Check for DNS leaks or blocks
- Use a DNS leak test website to confirm your DNS requests are being protected.
- If DNS leaks persist, try a different DNS provider or DNS over HTTPS in ProtonVPN settings, if available.
8 Test on a different network
- Try a different Wi‑Fi network or mobile hotspot to rule out local network blocks or ISP throttling.
9 Switch protocols or servers
- OpenVPN, WireGuard, and IKEv2 have different handshake patterns.
- In ProtonVPN settings, switch to an alternate protocol and try again.
- Switch to a different server or country to bypass regional blocks.
Advanced fixes for stubborn problems
10 Reinstall ProtonVPN with a clean profile
- Uninstall ProtonVPN completely.
- Remove residual files preferences, caches, and app data.
- Reboot, then install the latest version from the official site.
11 Check system clock and certificates
- An incorrect system clock can cause TLS errors.
- Sync time and date, then try again.
- Ensure trusted root certificates are up to date.
12 Review proxy or VPN conflicts
- Remove any extra VPN tools or proxies that could conflict with ProtonVPN.
- If you have multiple VPN profiles, disable the others.
13 Disable IPv6 temporary
- Some networks misbehave with IPv6 when a VPN is active.
- Disable IPv6 in your network settings temporarily while testing ProtonVPN.
14 Flush DNS and renew IP
- Windows: ipconfig /flushdns && ipconfig /renew
- macOS: sudo killall -HUP mDNSResponder
- Linux: sudo systemd-resolve –flush-caches
15 Check ProtonVPN server status
- There could be an outage affecting certain regions.
- Visit status.protonvpn.com or ProtonVPN support pages for updates and service notices.
Common errors and how to interpret them
- Error: “Could not connect to server” — likely server issues, network block, or protocol mismatch.
- Error: “Authentication failed” — wrong credentials or account issue; re-enter credentials.
- Error: “TLS handshake failed” — clock skew or firewall interference; verify time and firewall rules.
- Error: “DNS resolution failed” — DNS settings or network-level blocks; switch DNS or networks.
- Error: “Unsupported OS version” — upgrade your OS or use a compatible ProtonVPN client version.
Performance and privacy considerations
- ProtonVPN offers secure encryption and a no-logs policy, but performance depends on server load and distance.
- For best results, pick a nearby server with low latency and stable throughput.
- Enable kill switch to prevent unprotected data leaks if the VPN drops.
- Use split tunneling to route only certain apps through the VPN if bandwidth is limited.
Quick testing steps to verify ProtonVPN is working
- Perform a speed test with ProtonVPN connected to a nearby server and compare results to your baseline.
- Visit a site that shows your external IP to confirm it changes to the VPN’s IP address.
- Run a DNS leak test to ensure your DNS requests are protected.
- Check that your real IP address isn’t exposed when the VPN is connected.
Best practices to avoid future issues
- Keep ProtonVPN and your device OS updated.
- Regularly review firewall and security software settings to ensure VPN access.
- Create a short list of reliable servers and protocols you know work well for your location.
- Backup your ProtonVPN configuration if you use manual setup OpenVPN/WireGuard.
Quick reference cheat sheet
- If ProtonVPN won’t open: restart, update, verify account, check connection.
- If you see DNS issues: change DNS to 8.8.8.8/8.8.4.4 or 1.1.1.1, test on another network.
- If you have conflicts: remove other VPNs, disable conflicting security apps.
- If a server is slow: switch servers or protocol, retry later.
- If all else fails: reinstall ProtonVPN with a clean profile.
