- Prefer near-time servers with low load: Server load metrics in the app help you pick the least congested option.
- Disable IPv6 exit routing if you encounter leaks or instability: Some networks misroute IPv6 traffic, causing drops.
- Enable the kill switch with caution: It protects you if the VPN drops, but it can cause apparent disconnects when the tunnel flips. Use it to protect privacy, but test both states to see what works best for you.
- Split tunneling: For devices and use cases where you don’t need all traffic protected, you can exclude non-sensitive apps from VPN to improve stability and speed.
- Check router compatibility: If you’re on a home network, ensure your router firmware is up-to-date and supports VPN passthrough for the chosen protocol.
- Use a wired connection for desktop: If possible, use Ethernet instead of Wi‑Fi for more stable VPN sessions.
- Regular maintenance: Reboot your router and modem weekly or after long sessions to clear stale connections.
- Network troubleshooting checklist step-by-step
- Step 1: Confirm core internet access without VPN
- Can you browse normally? If not, fix the base connection first.
- Step 2: Update everything
- Update Proton VPN app and OS to the latest versions.
- Step 3: Try different servers and protocols
- Test 3–5 servers across 2 protocols, record latency and success rates.
- Step 4: Check for conflicting software
- Disable other VPNs, firewall rules, or antivirus modules that might block VPN traffic.
- Step 5: DNS sanity check
- Change DNS to a clean resolver 1.1.1.1 or 9.9.9.9 and flush DNS.
- Step 6: Reboot and observe
- After changes, reboot device and router if needed, then monitor stability for 24–48 hours.
- Step 7: Contact support if needed
- If issues persist, collect logs and contact Proton VPN support with details device, OS, app version, server, protocol, timestamps.
- Data-backed insights and industry context
- VPN usage trends: Global VPN usage continues to grow, with mobile devices accounting for a rising share of traffic. In 2025, mobile VPN usage increased by roughly 18% year over year in many regions, driven by privacy concerns and remote work needs.
- Server load impact: A well-distributed network with clear load indicators reduces disconnects by up to 40% on average, compared to highly congested servers.
- Protocol performance: WireGuard typically reduces latency by 20–60% and improves reliability on unstable networks versus traditional OpenVPN, particularly on mobile and under varying network conditions.
- Privacy considerations: Consistent VPN use reduces exposure to DNS leakage and IP leaks, which is a common reason users experience perceived disconnects or page load failures.
- Real-world examples and scenarios
- Scenario A: You’re on a crowded subway with unstable cellular data.
- Quick fix: Switch to a nearby WireGuard server, enable the kill switch, and avoid high-latency routes. Consider turning on split tunneling for non-critical apps to reduce VPN load.
- Scenario B: You’re gaming or streaming and notice stutters.
- Quick fix: Ping to the VPN server and switch to a less congested server, use a protocol with lower overhead, and potentially disable IPv6 to avoid leaks.
- Scenario C: You’re on a business network with strict firewall rules.
- Quick fix: Try a different protocol that uses common ports like WireGuard on UDP and check if the network allows VPN traffic. If blocked, contact IT for whitelisting or use a corporate VPN option.
