Before you dive into deeper fixes, use this quick checklist to gauge where the problem lies.
- Is Proton VPN installed correctly? If you recently updated your OS, the app might need a fresh install.
- Do you have a stable internet connection without the VPN? Try loading a webpage in your browser first.
- Are there any firewall or antivirus restrictions blocking the app? These can silently block VPN traffic.
- Is your device’s clock accurate? Some VPNs fail to authenticate if the system time is off.
- Are you behind a corporate proxy or network that blocks VPNs? Your network policy could be the culprit.

Performance and reliability tips: keep Proton VPN running smoothly
Beyond fixing the immediate issue, you want a stable, fast VPN experience.
- Use WireGuard where possible for better speed and reliability.
- Choose servers closer to your location for faster latency.
- Enable “kill switch” to protect your data if the VPN drops, but test it to ensure it doesn’t block legitimate traffic.
- Optimize DNS settings to avoid leaks and speed up lookups.
- Regularly clear old server favorites to avoid stale connections.
- Keep your device plugged into power when using VPN for laptops—some power-saving modes throttle performance.
Data and stats you can rely on
- On average, VPN usage shows 20–70% speed loss on OpenVPN and around 5–15% on WireGuard, depending on network conditions and server load.
- Proton VPN uses strong encryption and a strict no-logs policy, with a transparent privacy framework and transparent audits.
- Server load and geo-proximity heavily influence latency; choosing the right server matters more than you might expect.
