Common causes of Surfshark disconnects
- Unstable or flaky internet connection: If your base connection keeps dropping, the VPN will inevitably drop too.
- Protocol mismatches and server overload: Some servers or protocols can be unstable in certain regions or network environments.
- IP leaks or DNS leaks: Conflicts between your device DNS settings and the VPN can cause drops or disconnections.
- Firewall, antivirus, or router restrictions: Firewalls or ISP-grade traffic shaping can interrupt VPN traffic.
- IPv6 traffic bypassing the VPN: If IPv6 is enabled and not properly routed through the VPN, you can see leaks or disconnects.
- App conflicts or outdated software: Old Surfshark apps or conflicting VPNs can trigger disconnects.
- Router-level issues: If you’re using Surfshark on a router, firmware, MTU settings, or QoS rules can cause drops.
Quick-start fixes you can try now
- Check your internet stability: Run a quick speed test and ping check. If your baseline is unstable or you’re dropping packets, fix the underlying connection first modem reboot, moving closer to the router, or contacting your ISP.
- Update Surfshark to the latest version: An out-of-date app can have bugs that lead to disconnects. Install the latest release for your device.
- Switch protocols: If you’re on a heavy protocol like OpenVPN and you’re in a congested network, try WireGuard for speed and stability, or vice versa if you suspect a protocol issue.
- Change servers: Some servers are overloaded. Switch to a nearby server, or try a different country with similar content access to see if stability improves.
- Disable IPv6: Turn off IPv6 on your device or within Surfshark settings to prevent IPv6 leaks and ensure all traffic routes through the VPN.
- Enable Kill Switch: Make sure the VPN Kill Switch is on so your traffic doesn’t leak if the VPN temporarily disconnects.
- Disable conflicting VPNs or security tools: If you have another VPN or a firewall that interferes with VPN traffic, disable it temporarily to test stability.
- Reinstall Surfshark: If problems persist, a clean reinstall can clear corrupted config files.
- Check router settings if using a VPN on the router: Ensure the router firmware is up to date and your MTU is reasonable usually around 1500. Enable VPN pass-through if your router requires it.
- Test on different networks: Try a different Wi-Fi network or a mobile hotspot to determine if the issue is network-specific.
Protocol, server, and DNS settings to fix and optimize stability
- Protocol selection:
- WireGuard fast, efficient, good stability on mobile and many home networks
- OpenVPN UDP for speed, TCP for reliability in some restricted networks
- IKEv2 stable on many mobile networks. useful if you’re on iOS or macOS
- Server selection:
- Prefer nearby servers for lower latency. avoid servers with known overload or recent maintenance.
- Use Surfshark’s “Smart Location” or similar feature if available to automatically pick stable options.
- DNS handling:
- Use Surfshark DNS if available to prevent leaks.
- If you’re seeing DNS leaks, switch to a trusted DNS 8.8.8.8 / 1.1.1.1 within your device settings or Surfshark app.
Device-specific troubleshooting
- Windows:
- Update network drivers and Windows to the latest version.
- In Surfshark, switch to WireGuard, then try OpenVPN UDP if issues persist.
- Enable the Kill Switch and Auto-Connect on startup after a successful connection.
- Disable IPv6 in Network & Internet settings if you notice leaks.
- Check firewall rules. temporarily allow Surfshark executable through the firewall to test.
- macOS:
- Ensure macOS is updated and that you’ve installed Surfshark from the official site or App Store.
- Try switching protocols WireGuard vs OpenVPN and restarting the app.
- If you use Little Snitch or other network monitors, make sure Surfshark isn’t blocked.
- iOS:
- Update iOS and Surfshark. For iPhone users, IKEv2 or WireGuard tends to be reliable. try a different protocol if you’re seeing drops.
- Disable battery saver or low-power mode temporarily. it can throttle background VPN activity.
- Android:
- Check if you have background data restrictions on for Surfshark. allow unrestricted data usage in settings.
- Switch to a different protocol and a nearby server. Android devices sometimes show more stability with WireGuard.
- Clear app cache or reinstall if you see persistent disconnects.
- Linux:
- Use the CLI to switch protocols and verify that the service is running correctly.
- Check that the firewall isn’t blocking VPN traffic and that your MTU is properly configured 1440–1500 range often works well.
- Router-based VPN:
- Confirm your router firmware is up to date. old firmware can cause disconnects or instability.
- Make sure you’ve configured NAT and VPN pass-through correctly.
- If you’re using a custom router like OpenWRT or DD-WRT, verify VPN integrator modules and firewall rules aren’t blocking VPN traffic.
- Test with a direct device connection first. if it’s stable, migrate to router VPN with recommended settings.
Router and network environment tips
- Use a stable internet connection: A weak Wi-Fi signal or high jitter can cause VPN drops. If possible, switch to a wired connection for testing.
- Optimize MTU settings: MTU around 1450–1500 is a common sweet spot for VPNs. misconfigured MTU can cause packets to fragment and drop.
- Disable QoS or prioritize VPN traffic temporarily: Some routers’ QoS settings interfere with VPN flows. test with QoS disabled.
- Consider using a VPN-friendly DNS: If your router uses its own DNS, switch to a trusted DNS provider to prevent DNS-related issues.
- Test on multiple servers and networks: If one server consistently disconnects, there’s a good chance the issue is server or network-specific rather than a device problem.
Advanced troubleshooting steps
- Check for IP leaks: Use online tools to verify that all traffic routes via the VPN and that there are no WebRTC or DNS leaks.
- Review Surfshark app logs: Look for error messages or recurring codes that indicate the cause e.g., protocol negotiation failures, TLS errors, or handshakes.
- Temporarily disable CleanWeb: If you have ad/tracker blocking features enabled, they can sometimes interfere with connectivity on certain sites. Disable briefly to test.
- Recheck ISP throttling or firewall: Some ISPs restrict VPN traffic. consider a different port or protocol to bypass simple DPI-based blocks.
- Test with Surfshark’s “Obfuscated servers”: If you’re in a restricted network school, workplace, or country with VPN restrictions, obfuscated servers can help keep the connection steady.
What to do when Surfshark still disconnects
- Collect diagnostic information: Note your device, OS version, Surfshark version, protocol, server, IP, and time of disconnects. This helps support diagnose issues faster.
- Reproduce the issue: Try the same server and protocol across different networks to identify whether the problem is network-specific or server-specific.
- Contact Surfshark support: Provide your diagnostic details, steps you’ve already tried, and any error messages you saw. They can offer tailored guidance or investigate server-side issues.
Why a disconnection might appear briefly and what it means
- Short disconnects are often normal as your device re-establishes a connection, but frequent or extended disconnections indicate something deeper network instability, protocol negotiation, or server overload.
- If you notice a consistent pattern e.g., every 5 minutes or when streaming, that signals a specific trigger—buffering routines, DPI detection, or a server that’s overloaded.
Best practices to keep Surfshark stable over time
- Regular updates: Always run the latest Surfshark app and keep your device OS current.
- Consistent server rotation: If your connection drops on a single server, rotate to a different one and monitor performance.
- Routine DNS hygiene: Use Surfshark DNS or a trusted alternative to avoid leaks that cause disconnections.
- Automated behavior: Use Auto-Connect with a reliable protocol and a nearby server to reduce manual intervention.
- Maintain your hardware and network: Clean cables, stable modems, and low interference environments help VPNs stay up.
Frequently Asked Questions
Frequently Asked Questions
Why does Surfshark disconnect when I try to watch streaming content?
Streaming often requires a stable, high-bandwidth connection. If the server is overloaded or your protocol isn’t optimized for streaming, you may see disconnects. Switch to a nearby server, try WireGuard, and ensure your DNS isn’t leaking. Also consider using the Auto-Connect feature with a nearby server to maintain a steady connection during playback.
How can I fix Surfshark disconnects on Windows 11?
Ensure you have the latest Surfshark app and Windows updates. Try switching protocols WireGuard or OpenVPN UDP, enable Kill Switch, disable IPv6, and test with a different server. If issues persist, reinstall Surfshark and reset your network adapter.
Is it safe to disable IPv6 to fix disconnections?
