How to fix specific issues people commonly report
- Issue: “Proton VPN wont open at all”
- Solution: Reinstall, check for conflicting software, and try a clean boot to isolate startup issues.
- Issue: “Connection stuck on connecting/unresponsive”
- Solution: Change server, change protocol, disable IPv6, and test with a mobile hotspot.
- Issue: “DNS leaks or slow DNS resolution”
- Solution: Enable DNS protection within Proton VPN, flush DNS, and consider using a trusted DNS 1.1.1.1, 9.9.9.9.
- Issue: “App crashes on launch”

Performance and reliability tips
- Always use the latest protocol where possible; WireGuard-based protocols tend to be faster and more reliable than older ones.
- Choose a server geographically close to you to reduce latency, but consider a few tests to find the best performance.
- Enable auto-connect on startup if you’re worried about forgetting to turn the VPN on.
- Use split tunneling if available to route only certain apps through Proton VPN, reducing overhead for others.
- Test DNS tools to ensure there’s no DNS leakage when connected.
- If you’re on a network with heavy restrictions, using a different port or protocol can help bypass blocks.
Security and privacy best practices
- Regularly review app permissions to ensure Proton VPN has only the necessary access.
- Keep your device’s security software updated and ensure you’re not running conflicting VPN services.
- Verify the VPN’s kill switch is enabled if you’re on an untrusted network to avoid data leaks.
- Check the app’s privacy policy and terms to understand how your data is handled when connected.
