Update the Proton VPN app to the latest version on all devices.
Restart the app and, if needed, reboot the device.
Switch servers or change the VPN protocol e.g., from OpenVPN to WireGuard or vice versa.
Disable IPv6 on the device or within the app if you suspect IPv6 leaks.
Check your firewall or antivirus settings to ensure Proton VPN isn’t blocked.
Ensure your internet connection is stable without the VPN first, then reconnect.
Clear app cache/data on mobile devices or reinstall the app if problems persist.
Verify that you are logged in with an active Proton account and that your subscription is valid.

Troubleshooting by device

Windows

Check Proton VPN service status in Task Manager and ensure the Proton service is running.
Run the Proton VPN app as Administrator to avoid permission issues.
Temporarily disable Windows Firewall or create a rule allowing Proton VPN.
If DNS leaks occur, set Proton VPN to use its own DNS servers and disable your primary DNS server.
Use WireGuard protocol for better speed and stability; OpenVPN can be slower on some networks.
Check for conflicting VPNs or network adapters and disable unused ones.

macOS

Ensure macOS Firewall isn’t blocking Proton VPN; check System Preferences > Security & Privacy > Firewall.
Reinstall Proton VPN for a clean configuration, especially after a macOS update.
If the app crashes, run the app in reduced graphics mode or reset preferences by deleting ProtonVPN’s config files.
Verify permissions for required network extensions in macOS System Preferences.

Android

Grant necessary permissions for the Proton VPN app VPN permission, storage, etc..
Try switching from Battery Saver modes to Normal performance mode.
Clear cache and data for the Proton VPN app; reinstall if needed.
Use a different server location or protocol WireGuard is preferred on mobile for speed.

iOS

Check iOS VPN configuration: Settings > VPN, ensure Proton VPN is configured correctly.
Disable Low Power Mode and background app refresh if you’re experiencing drops or disconnects.
Reset network settings if persistent issues occur Settings > General > Reset > Reset Network Settings.

Protocols and server considerations

WireGuard vs OpenVPN: WireGuard generally offers better speed and stability on mobile and many desktops, but some networks might block it; OpenVPN provides broader compatibility in strict networks.
UDP vs TCP: UDP is faster but less reliable on lossy networks; TCP can be more stable in networks with limited UDP support.
Server load: If a server is overloaded, you’ll see slow speeds or dropped connections. Switch to a less crowded server or region.
P2P/server type: Some servers are optimized for streaming, others for torrenting or general browsing. Choose based on what you’re doing.
Protocol negotiation: If automatic protocol selection isn’t giving you a stable connection, manually switch protocols.

DNS and privacy leaks explained

DNS leaks happen when DNS requests bypass the VPN tunnel and go to your local ISP’s DNS servers. This can reveal browsing activity.
IP leaks occur when your real IP is exposed due to misconfigured settings or IPv6 leaks.
Solutions:
- Enable DNS leak protection in Proton VPN settings and use Proton’s DNS servers.
- Disable IPv6 at the device level or within Proton VPN settings if you see IPv6 leaks.
- Test for leaks using reputable online DNS/IP leak tests.

Networking basics you should know

What VPN does: Creates an encrypted tunnel between your device and a VPN server, masking your IP and encrypting traffic.
Kill switch: A feature that blocks all traffic if the VPN disconnects to prevent leaks.
Split tunneling: Lets you choose which apps use the VPN and which don’t; useful for streaming or local access.
DNS resolution: Your DNS requests can reveal websites you visit; using a VPN with DNS protection helps keep this private.

Performance optimization tips

Choose servers geographically closer to you for lower latency.
Prefer WireGuard where available for speed; switch to OpenVPN if you encounter issues with WireGuard on a specific network.
Disable unused background apps that consume bandwidth.
Use a wired connection when possible to minimize wireless interference.
Check router settings: ensure you don’t have QoS or firewall rules limiting VPN traffic.
Update router firmware and VPN client if your setup supports it.

Security and privacy best practices

Enable the Proton VPN Kill Switch to prevent traffic leaks if the VPN drops.
Use fresh credentials and enable 2FA on your Proton account to prevent unauthorized access.
Regularly review connected devices and session logs for any suspicious activity.
Avoid free or questionable VPNs; Proton VPN’s paid plans typically offer stronger privacy guarantees and more robust features.
If you’re in a restrictive network schools, workplaces, try obfuscated servers if Proton offers them to bypass deep packet inspection.

Advanced fixes for stubborn problems

Flush DNS caches on your devices to remove stale DNS records that may cause connection issues.
Manually configure DNS servers in your OS to known fast DNS providers e.g., 1.1.1.1 or 8.8.8.8 and re-test Proton VPN.
Reset network settings on your device: this clears misconfigured VPN adapters and routes.
Check for router-level VPN blocks or ISP throttling; test on a different network hotspot or public Wi-Fi to isolate the problem.
Review logs: Proton VPN app logs can reveal authentication failures, certificate issues, or protocol mismatches.

Performance and reliability checklist

Have you tried multiple servers in different regions?
Have you tested both protocols WireGuard and OpenVPN to compare stability?
Is IPv6 disabled to prevent leaks?
Is the Kill Switch enabled and functioning correctly?
Are you using a supported app version on your device?
Are there any conflicts with other VPNs or firewall rules?
