- WireGuard tends to be faster but may have compatibility issues on some networks
- Split tunneling
- If Proton VPN supports split tunneling, consider routing only sensitive traffic through the VPN
- Kill switch and leak protection
- Ensure these are enabled to prevent IP leaks in case the tunnel drops
- Check server status
- Sometimes Proton VPN servers are down for maintenance; try a different region or server
- Logs and diagnostics
- Enable logs in Proton VPN and share them with support if you need help
- Compatibility mode
- On Windows, try compatibility settings for Proton VPN if you see crashes after updates
Proton VPN account and service checks

Security considerations
