Staying aware of uptime metrics and using the right server type can reduce drops.

Common reasons Proton VPN disconnects

Server load and maintenance: High traffic or routine maintenance can force disconnects or reconnects.
network compatibility: Some routers or networks block VPN protocols or throttle VPN traffic.
Protocol and server settings: The chosen protocol OpenVPN, WireGuard, etc. or server type can cause drops under certain conditions.
DNS leaks or IPv6 issues: Misconfigured DNS or IPv6 handling can trigger disconnects.
App and OS conflicts: Background apps, firewall rules, or outdated clients can interrupt VPN tunnels.
IP reputation and routing: Some exit nodes get flagged, causing automatic drops by the client for safety.
Power or sleep states: Laptops or mobile devices resuming from sleep can reset VPN connections.
Wholesale misconfigurations: Incorrect credentials or corrupted VPN profiles can lead to repeated drops.

Top troubleshooting steps quick wins

Check Proton VPN server status

Switch to a different server in the same country or try a less crowded region.
Avoid servers flagged for maintenance or known reliability issues.
If you’re on a specific server, try the “recommended” or “Fastest” option.

Change VPN protocol and server type

If you’re using OpenVPN UDP, switch to OpenVPN TCP or try WireGuard, then test stability.
Some networks favor WireGuard; if you’re on a flaky connection, TCP-based protocols can be more robust.

Disable IPv6 and enforce secure DNS

Disable IPv6 on your device or within Proton VPN settings if supported.
Use Proton VPN’s DNS or switch to a trusted DNS provider to prevent leaks and conflicts.

Verify kill switch and app firewall rules

Ensure the VPN kill switch is enabled to prevent leaks when the VPN drops.
Temporarily disable third-party firewalls or antivirus software to test if they’re causing drops.

Reinstall or update Proton VPN

Update to the latest Proton VPN client to get bug fixes and performance improvements.
If problems persist, reinstall the app and re-import your profile.

Router and network tweaks

Reboot the router to clear any stale state or congested connections.
If you’re on Wi‑Fi, move closer to the router or switch to a wired Ethernet for testing.
Enable UPnP, or open necessary ports if your router has strict firewall rules consult Proton VPN docs for protocol ports.

Power and device considerations

On laptops, prevent sleep during VPN sessions; adjust power settings to avoid automatic sleep or hibernate.
On mobile, ensure background data isn’t restricted for the Proton VPN app.

Check for other apps causing interference

Turn off other VPNs, privacy extensions, or network-monitoring software.
Close bandwidth-heavy apps cloud backups, streaming to see if the VPN stabilizes.

Test for DNS and IP leaks

Use Proton VPN’s built-in DNS leak test or an external test site to verify there’s no leak during operation.
If leaks appear, switch DNS settings or disable IPv6 to close the leaks.

Review ISP and network limitations

Some ISPs throttle VPN traffic or block certain protocols. In that case, try WireGuard or stealth modes if available, or connect on a different network.

Device-specific guides
Windows

Prefer WireGuard or OpenVPN with UDP for speed; if drops occur, switch to TCP.
Turn off Battery Saver mode and set Proton VPN to run in the foreground.
Ensure you have the latest Windows updates and that your network drivers are current.

MacOS

Use the latest Proton VPN client and try both WireGuard and OpenVPN.
Disable macOS firewall or configure it to allow Proton VPN connections.
Ensure “Allow incoming connections” is set properly for the VPN app.

Android

Check battery optimization settings and whitelist Proton VPN.
Test both WireGuard and OpenVPN; some devices handle one protocol more reliably.
Clear the app cache and storage if you notice odd disconnects.

IOS

Disable Low Power Mode during VPN sessions.
Reinstall Proton VPN if problem persists, and ensure iOS is updated.
Check system-wide VPN settings and make sure Proton VPN has full permission.

Router-based fixes

If you’re on a home router, update its firmware.
Use a router that supports VPN passthrough for the protocol you’re using.
Consider enabling a separate VPN-enabled router for your devices to isolate VPN traffic.

Best practices for reliable Proton VPN performance

Use the “Fastest” or “Recommended” server when you’re just browsing to maximize stability.
For streaming or gaming, choose servers optimized for those activities if Proton offers them.
Keep your VPN app and device software updated; patches often fix disconnect bugs.
Use a trusted DNS option to prevent leaks and reduce DNS-related disconnects.
If you frequently switch networks, consider enabling auto-reconnect and a stable protocol profile.

Data and statistics to consider

VPN reliability studies show that protocol choice can affect disconnect frequency: WireGuard tends to be more stable on mobile networks with fewer drops than OpenVPN in some environments.
Server load is a major factor; many VPN users experience improved stability by switching to a less crowded server region.
DNS leaks occur in a noticeable portion of VPN sessions; enabling the VPN’s DNS or disabling IPv6 reduces leaks and disconnects.

Advanced troubleshooting for power users

Check Proton VPN logs for disconnect timestamps and correlate with network events.
Run a continuous ping to a stable host 8.8.8.8 with and without VPN to measure latency variance and packet loss during drops.
Inspect MTU size: if packets are fragmented often, try a smaller MTU value in the VPN profile to prevent drops.
Use a dedicated VPN profile for specific workloads work, streaming, gaming to keep settings consistent.

When to contact support

If you’ve gone through the above steps and still experience frequent disconnects, gather logs:
- Proton VPN version
- OS version and device model
- Server location and protocol used
- Approximate time of disconnects and any error messages
Share these with Proton VPN support along with any screenshots of error messages or logs.
