Symptom and quick diagnosis
If Proton VPN keeps disconnecting, you’re likely facing one of a few predictable issues: Why VPN Sales Are Skyrocketing in Hong Kong and What It Means for 2026: Trends, Tips, and Real-World Impacts

Server overload or unstable servers: If too many users share the same exit node, connections drop.
Protocol choice and compatibility: WireGuard is fast but sometimes unstable on certain networks; OpenVPN is stable but slower.
DNS or IP leaks: Some networks block VPNs or misroute traffic, causing drops.
Local network issues: Weak Wi-Fi, contention on your router, or VPN blockages by ISPs.
App or OS quirks: Outdated app versions or OS network settings can trigger disconnects.

The quick diagnosis checklist

Are you seeing disconnects on multiple servers or just one? If it’s multiple servers, it’s more likely a device or network issue. If it’s just one server, try others.
Does disconnecting happen during specific activities streaming, gaming or at random times? Activity-based drops often point to bandwidth or QoS issues.
Are you on Wi‑Fi or mobile data? Try a different network to rule out your current network as the culprit.
Have you updated Proton VPN recently? Outdated apps can behave badly with newer OS updates.

Step-by-step fix guide
Follow these steps in order. If a step resolves the issue, you can skip the rest.

Update everything

Update Proton VPN to the latest version on all devices.
Update your OS Windows, macOS, iOS, Android to the latest stable version.
Update router firmware if you manage your own home network.

Switch protocols and servers

In Proton VPN, try a different protocol:
- If you’re on WireGuard and experiencing drops, switch to OpenVPN TCP for stability.
- If you’re on OpenVPN and need speed, try WireGuard again and monitor.
Connect to a different server, preferably one geographically closer to you or one labeled as “recommended” by Proton VPN.

Disable conflicting software

Temporarily disable firewall or antivirus VPN-related modules to rule out interference.
Some security suites block VPN tunnels. If you’re running one, add Proton VPN as an allowed app.

DNS and IP leak checks

Enable DNS leak protection in Proton VPN settings.
Use the built-in DNS in Proton VPN, or set a trusted DNS like 1.1.1.1 or 8.8.8.8 as a fallback on your device after turning off VPN to test.

Network router and Wi‑Fi tips

Restart your router and modem.
If you have VPN blocks or strict firewall rules on your router, enable UPnP or put Proton VPN on a DMZ if you know what you’re doing be cautious.
Prefer a wired connection when possible for stability.
If you’re on a 2.4 GHz network, try 5 GHz if your router supports both.

Reinstall Proton VPN

Uninstall Proton VPN completely, then reinstall the latest version.
On mobile, clear app data and cache before reinstall if you notice odd behavior.

Check device-specific quirks

Windows: Disable IPv6 if you’re not using it, sometimes it can conflict with VPN tunnels.
macOS: Turn off VPN-related SIP or firewall rules temporarily to test, then re-enable after testing.
iOS/Android: Ensure battery saver modes are disabled for VPN apps; some OS power-saving features kill background VPN activity.

Check for background apps and bandwidth

Close other bandwidth-heavy apps cloud backups, updates, large downloads.
Pause syncing services like OneDrive, Google Drive, iCloud during VPN use to reduce drops.

Test with a clean environment

Boot into Safe Mode with networking Windows or Safe Mode macOS and test Proton VPN to determine if background services are causing issues.

Contact Proton VPN support

If you still see disconnects, collect logs from Proton VPN Settings > Diagnostics or Help, your device model, OS version, and a few recent server names. Reach out to Proton VPN support with this information for targeted help.

Protocol and server considerations

WireGuard often provides the best speed, but stability can vary by network and server. If you notice intermittent drops, switch to OpenVPN TCP to improve reliability.
For streaming, use servers labeled for media or those close to your location. Some streaming services attempt to block VPNs; a stable server with less congestion helps.
Enable “Always-on VPN” or “Auto-connect” only after you’ve confirmed a stable configuration to avoid repeated disconnects on startup.

Device-specific optimization tips

Windows:
- Ensure you’re not running multiple VPN clients at once.
- Check Windows Firewall rules to ensure Proton VPN isn’t blocked.
- Set the VPN to run with elevated permissions Run as administrator if recommended by Proton VPN.
macOS:
- Reset network settings if you notice persistent DNS issues.
- Check that you’re not using a conflicting VPN profile in System Preferences > Network.
iOS and Android:
- Keep the app updated; OS updates can change how VPNs function.
- Check energy saver settings, as VPNs can be killed by aggressive background restrictions.
- If you use data saver modes, disable them for VPN use.

Streaming, gaming, and work: keeping the connection stable Surfsharks bypasser feature lands on ios unlock smarter vpn usage

For streaming, choose servers labeled for streaming or ones with high stability ratings. If Buffering starts, switch servers or protocols.
For gaming, lower latency is key. Prefer nearby servers and consider WireGuard for speed, then switch if you hit drops.
For work, especially on video calls, consider enabling Always-On VPN and selecting a server with low jitter and high reliability.

Network health and external factors

ISP throttling can cause VPN drops. If you suspect this, test using a full-speed test or switch to a different network temporarily to compare.
Public Wi‑Fi networks are notorious for blocking VPN traffic. When using such networks, pick servers with strong obfuscation features if available.
If you’re in a country with strict internet censorship, ensure you’re using Proton VPN’s obfuscated servers or other privacy-focused settings the service offers.

Maintenance and long-term stability

Regularly clear outdated server lists and refresh your server connections to avoid stale routes.
Schedule periodic reboots of your router and devices to reset stuck network states.
Keep a minimal number of active VPN profiles on your devices to avoid conflicts.

Useful statistics and data

VPN drop rates on average across popular services vary, but a well-configured Proton VPN setup usually achieves 95–99% uptime on stable connections.
WireGuard is generally 20–60% faster than OpenVPN depending on network conditions, but OpenVPN tends to be more consistent on flaky networks.
In crowded areas with many users, server load can spike dramatically, leading to disconnections; connecting to a less crowded server often fixes this.

Additional tips for reliability

Schedule periodic re-authentication if your device requires it; some sessions drop when token refreshes fail.
If you’re using multiple security tools, consider a temporary disablement during VPN testing to isolate the cause.
Use a preferred DNS with VPN enabled to prevent leaks and ensure proper routing.
