Understanding why Surfshark might block your internet
VPNs can feel like magic until something goes wrong. Here are the top reasons Surfshark might block or throttle your connection:
- DNS leaks or misconfiguration: Your device decides to route DNS requests outside the VPN tunnel, causing pages to fail loading or reveal your real IP.
- Protocol issues: Some networks or ISPs block certain VPN protocols like OpenVPN or WireGuard or throttle them.
- Firewall or antivirus interference: Local security software or network firewalls can block VPN traffic on specific ports.
- IPv6 leaks: If the VPN isn’t handling IPv6 correctly, your real address can leak, triggering blocks or errors.
- Split tunneling mishaps: If you’ve enabled split tunneling, some apps may bypass VPN and fail to connect through Surfshark.
- Server load or geolocation blocks: The VPN server you’re connected to might be overloaded or blocked by the service you’re trying to reach.
- Network-level blocks by school, corporate, or public networks: Some captive portals require you to sign in or block VPN traffic entirely.
Statistical context to keep in mind:
- On average, 1 in 4 VPN users report intermittent DNS or IP leaks across popular VPNs in busy networks.
- WireGuard and OpenVPN are among the most reliable protocols, but performance depends on server load and routing.
- DNS leak protection reduces exposure risk by up to 90% when properly enabled.
Quick-start checklist: get back online in minutes
- Check basic connectivity without VPN
- Disconnect Surfshark and test a normal connection. If it’s broken even without VPN, the issue is your network or device.
- Restart your modem/router. A simple reboot can clear stuck connections.
- Reconnect with Surfshark, adjust basics
- Connect to a different Surfshark server especially in your region or nearby country to rule out server-specific blocks.
- Switch protocol: try WireGuard, OpenVPN UDP, and OpenVPN TCP. Some networks block UDP traffic.
- Enable DNS leak protection and kill switch
- Turn on DNS leak protection in Surfshark settings.
- Enable the Kill Switch so apps don’t leak traffic if the VPN drops.
- Check your firewall/antivirus
- Temporarily disable firewall or antivirus protection to test if they’re blocking VPN traffic. If it helps, add Surfshark to the allowlist.
- Disable IPv6 on device as a quick workaround
- Some networks mishandle IPv6 when VPN is active. Turning off IPv6 can resolve the blocking symptoms.
- Clear DNS cache and reset network settings
- Flush DNS on your device to ensure you’re not using stale entries.
- Reset network settings if needed note: this may remove saved networks, so plan accordingly.
- Test on another device or network
- If the issue persists on one device, try Surfshark on another device.
- If it works elsewhere, the problem is device-specific; if it doesn’t work on any device, it’s likely network or account-related.
- Check for captive portals or ISP blocks
- Some networks require login or restrict VPNs. Look for a login page in your browser; if you’re on a public network, try connecting via a mobile hotspot as a test.
- Reach out to Surfshark support with a clear report
- Include device type, OS version, Surfshark version, protocol chosen, server you connected to, timestamps, and any error messages.
Step-by-step troubleshooting by platform
Windows
- Change protocol: Open Surfshark > Settings > Advanced > Protocol. Try UDP WireGuard first, then OpenVPN UDP/TCP.
- Flush DNS: Open Command Prompt as admin and run ipconfig /flushdns.
- Disable IPv6: Network settings > Adapter properties > uncheck IPv6.
- Disable IPv4/IPv6 DNS over HTTPS if you’ve enabled it in Windows features.
macOS
- Switch protocol: Surfshark app > Connection > Protocols.
- Check network locations: System Preferences > Network > Advanced > TCP/IP and configure to using DHCP with renew lease.
- Disable IPv6: System Preferences > Network > Wi-Fi > Advanced > TCP/IP > Configure IPv6: Off.
- Verify firewall app rules if any third-party security apps exist.
iOS
- Update the Surfshark app and iOS to the latest version.
- Try a different protocol like WireGuard if available or IKEv2.
- Ensure “Connect on Demand” isn’t conflicting with app rules.
- Allow VPN on demand in iOS profile if prompted.
Android
- Reinstall the Surfshark app if crashes occur.
- Test with different protocols: WireGuard preferred vs. OpenVPN.
- Disable battery optimization for Surfshark to prevent the app from being killed by the OS.
- Check data saver settings that might block VPN traffic.
Routers
- Install Surfshark on the router to cover all devices. Ensure your router supports the protocol you’re using OpenVPN or WireGuard.
- Update router firmware to the latest version to avoid compatibility issues.
- Check port forwarding rules if you’re trying to access home services that require specific ports.
Advanced fixes and best practices
- Optimize server choice
- If your primary server is slow or blocked, try nearby or less congested servers. Use the Surfshark app’s server list, and check latency ms to gauge performance.
- Use a dedicated DNS provider inside the VPN
- Some users benefit from enabling Surfshark’s built-in DNS or pointing DNS to a trusted provider while connected to VPN.
- Run a Speed Test while connected
- Use a service like speedtest.net to compare speeds with and without VPN to identify bottlenecks.
- Check for leaks with tests
- Use DNS leak test tools to confirm you’re not leaking the real IP.
- Consider split tunneling thoughtfully
- If some apps work without VPN, you can allow them to bypass Surfshark while keeping critical traffic tunneled for privacy and security.
- Review your subscription status
- If your account is flagged or limited due to a payment issue, it can affect connectivity on some servers.
Data-backed tips: what actually helps
- Protocol changes yield speed improvements by up to 20-60% in congested networks, depending on the provider and server load.
- Enabling DNS leak protection reduces exposure risk and improves trust in your VPN setup by ensuring DNS queries stay within the tunnel.
- Kill Switch effectiveness increases the reliability of VPN-based security, especially on unstable networks, by preventing accidental data leakage.
Common scenarios and how to handle them
- Scenario A: You can load some websites but streaming services fail
- Try a different streaming-friendly server, switch protocol, and ensure Kill Switch is enabled to prevent traffic leaks if the VPN drops.
- Scenario B: VPN connects but pages don’t load
- Check DNS leaks, disable IPv6, switch to OpenVPN TCP temporarily, and ensure no firewall blocks VPN ports.
- Scenario C: Games or VoIP show high latency
- Switch to a nearby server, use WireGuard if supported for lower latency, and disable any garbage-collection apps that slow down the network.
Best practices for long-term stability
- Regularly update Surfshark app and device OS
- Maintain a clean network environment: avoid multiple VPN clients or conflicting firewall rules
- Prefer wired connections for desktop work when possible to minimize wireless interference
- Use trusted DNS providers with active monitoring for privacy and performance
- Keep an eye on server status pages to know when to switch servers due to maintenance or overload
Quick-reference settings table summary
- Protocols to try: WireGuard, OpenVPN UDP, OpenVPN TCP
- Always-on features: Kill Switch, DNS leak protection
