Your Surfshark VPN stopped working, and now every device in your household is exposed. Don’t panic, most fixes take under five minutes.
When Surfshark VPN fails to connect, the cause almost always traces back to one of four issues: an outdated app version, a protocol mismatch with your local network, stale DNS cache entries, or IPv6 leaking past the VPN tunnel. Start by switching your VPN protocol from WireGuard to OpenVPN (TCP), then restart the Surfshark background service. If you see error code P0017, reinstall the app to reset the virtual network adapter. These steps resolve roughly 95% of “Connection Failed” loops reported by users in 2026.
This guide walks you through every fix, from basic server switches to advanced DNS-over-HTTPS configurations, so you can restore secure connections across your laptops, Firesticks, and smartphones fast.
Key Takeaways
- Surfshark VPN not working is usually caused by outdated apps, protocol mismatches, DNS cache issues, or IPv6 leaks—with a quick protocol switch from WireGuard to OpenVPN TCP resolving 95% of connection failures.
- Switching your VPN protocol and rebooting your device eliminates the majority of connectivity problems, while a clean reinstall of Surfshark fixes persistent background service errors like P0017.
- IPv6 dual-stack conflicts are the most common advanced cause of false ‘connection failed’ errors, and disabling IPv6 at the adapter level is the single most effective fix for modern operating systems.
- Update Surfshark to version 5.0+ for compatibility with current processors and Apple M4/M5 Silicon chips, and always configure DNS to ‘Automatic’ to prevent manual DNS entries from overriding Surfshark’s internal DNS.
- Network restrictions and restrictive firewalls can be bypassed using Surfshark’s NoBorders mode with obfuscated servers, while restrictive networks may require OpenVPN TCP on port 443 instead of WireGuard.
Surfshark’s unlimited device policy makes it a favorite for households running VPN protection on every screen. But that same broad coverage means one bad update or ISP-level interference can cascade failures across all your hardware simultaneously. Whether you’re a digital nomad stuck behind a hotel firewall or a family trying to stream in 4K, understanding why Surfshark breaks helps you fix it faster.
The troubleshooting steps below follow a diagnostic hierarchy. You’ll start with the most common culprits, network restrictions and protocol issues, then move into advanced DNS and manual configuration fixes. Each section targets a specific failure mode so you can skip directly to your problem.
Common Causes of Surfshark VPN Connectivity Issues
Before you start changing settings, identify what’s actually going wrong. Surfshark VPN connection failures fall into four broad categories.
Network Restrictions and Interference
Restrictive networks, corporate firewalls, hotel Wi-Fi portals, and ISP-level deep packet inspection, block VPN traffic aggressively. If you’re traveling in a country with heavy internet censorship, standard VPN protocols get flagged and dropped. Surfshark’s NoBorders mode exists specifically for this scenario. It automatically selects obfuscated servers that disguise VPN traffic as regular HTTPS. If NoBorders isn’t activating, your app version may be outdated, or the feature may need manual toggling under Settings > Advanced. ISP throttling can also degrade your connection to the point where the VPN handshake times out before completing.
Protocol and Server Compatibility
Surfshark supports WireGuard, OpenVPN (UDP/TCP), and IKEv2. Each protocol behaves differently depending on your network. WireGuard is fastest on clean connections but struggles on networks that block UDP traffic. OpenVPN TCP, while slower, punches through more firewalls because it uses port 443, the same port as regular web traffic. Server compatibility matters too. Overloaded servers cause timeouts, and some server locations perform poorly during peak hours.
IPv6 Interactions
Many users don’t realize their router broadcasts IPv6 addresses alongside IPv4. Surfshark primarily tunnels IPv4 traffic. If your device sends DNS queries over IPv6, those requests bypass the VPN entirely, causing DNS leaks or connection instability. This is a particularly common issue on Windows 11/12/13 systems where IPv6 is enabled by default.
Software Conflicts
Third-party antivirus programs, Windows Defender’s firewall, and even other VPN remnants can block Surfshark’s virtual network adapter. If you previously used another VPN service, leftover TAP or TUN drivers may conflict with Surfshark’s WireGuard adapter. The Surfshark Bypasser (split tunneling) feature can also malfunction if another app controls network routing.
Effective Troubleshooting Steps
Work through these fixes in order. Each step eliminates a category of problems.
Change VPN Protocol
Open Surfshark, go to Settings > VPN Protocol, and switch from your current protocol. If you’re on WireGuard, try OpenVPN (TCP). If you’re on OpenVPN, try IKEv2. This single change fixes the majority of “Surfshark VPN stuck on Connecting” issues because it forces a completely different handshake method.
| Protocol | Best For | Drawback |
|---|---|---|
| WireGuard | Speed on open networks | Blocked on restrictive Wi-Fi |
| OpenVPN TCP | Firewall penetration | Slower than WireGuard |
| OpenVPN UDP | Balanced performance | Blocked by some ISPs |
| IKEv2 | Mobile connections | Limited server support |
Switch to Alternative Servers
Don’t keep reconnecting to the same server. Surfshark operates over 3,200 servers across 100+ countries. Try a server in a nearby country or a different city within the same country. For streaming, use Surfshark’s “Fastest Server” option, which auto-selects based on latency and load. If your Static IP connection keeps timing out, switch to a dynamic server temporarily to confirm the issue isn’t server-specific.
Update or Reinstall the Application
Outdated Surfshark apps are the top cause of background service errors, including the P0017 error code. Update to version 5.0+ to ensure compatibility with current Hurricane processors and Apple M4/M5 Silicon chips. If updating doesn’t help, perform a clean reinstall:
- Uninstall Surfshark completely
- Restart your device
- Delete any remaining Surfshark folders from AppData (Windows) or Application Support (Mac)
- Download the latest version from Surfshark’s official site
- Install and log in fresh
This process resets the virtual network adapter and clears corrupted diagnostic logs.

Reboot Devices and Applications
It sounds basic, but rebooting clears stale network states. Restart your router, then your device, then launch Surfshark. On Firestick, force-stop the Surfshark app before reopening. If your kill switch is blocking all internet after a failed connection, rebooting is often the fastest way to restore access while you troubleshoot further.
Resolving Advanced Configuration and Network Problems
If basic steps didn’t work, you’re likely dealing with a deeper network or configuration issue.
Correct DNS Settings
Surfshark runs its own DNS on every server to prevent leaks. But if your device has manually configured DNS entries (like Google’s 8.8.8.8 or Cloudflare’s 1.1.1.1), they can override Surfshark’s DNS and cause resolution failures. Set your network adapter’s DNS to “Automatic” or point it to Surfshark’s internal DNS. For 2026 browsers with DNS-over-HTTPS enabled by default, check that your browser’s DoH settings don’t conflict, go to your browser’s privacy settings and disable custom DoH when Surfshark is active.
To flush your DNS cache on Windows, open Command Prompt as admin and run:
ipconfig /flushdnsipconfig /releaseipconfig /renewnetsh winsock reset
Disable IPv6 on Your Device
Go to your network adapter settings and uncheck Internet Protocol Version 6. On Windows: Network Connections > Adapter Properties > uncheck IPv6. On macOS: System Settings > Network > Advanced > TCP/IP > Configure IPv6: Link-local only. This eliminates IPv6 DNS leaks and stabilizes the VPN tunnel.
Manage Cookies and Browser Cache
Streaming services like Netflix and Disney+ store location data in cookies. Even with Surfshark connected, old cookies can reveal your real location and trigger VPN detection. Clear your browser cache and cookies before connecting, or use Surfshark’s CleanWeb feature alongside a private browsing window.
“Cleared cookies and suddenly Netflix stopped showing the proxy error. The VPN was working fine the whole time, it was cached location data causing the block.” via r/VPN
Manual VPN Configuration
If the Surfshark app refuses to cooperate, configure WireGuard or OpenVPN manually. Download your configuration files from Surfshark’s manual setup page. Import them into the standalone WireGuard client or OpenVPN Connect app. Manual configuration bypasses the Surfshark app entirely, which isolates whether the problem is app-specific or network-level.
For hardware-level reliability, consider a dedicated VPN router like the GL.iNet GL-MT6000 Flint 2 to run Surfshark at the router level, protecting every device without individual app installs.
When to Seek Additional Help or Alternatives
Contacting Surfshark Customer Support
If you’ve exhausted every fix above, contact Surfshark’s 24/7 live chat support through the app or their website. Before reaching out, collect your diagnostic logs: go to Settings > App Info > Send Diagnostic Logs. Providing these logs dramatically speeds up resolution. Surfshark support can check server-side issues, reset your Alternative ID if you’re experiencing login synchronization errors, and push configuration updates directly.
Checking for Service Outages
Sometimes the problem isn’t on your end. Surfshark occasionally experiences regional server outages during maintenance or after DDoS attacks. Check Surfshark’s status page and platforms like Downdetector for real-time reports before spending hours troubleshooting a server-side issue.
Considering Alternative VPN Providers
If Surfshark consistently fails on your network setup, it’s worth testing alternatives to isolate the problem. NordVPN and ExpressVPN both offer 30-day refund periods. But, Surfshark’s unlimited device policy and competitive feature set (CleanWeb, MultiHop, NoBorders) make it worth persisting through most issues.
For users working from a dedicated home office, upgrading your network hardware can prevent many VPN issues entirely. A reliable Wi-Fi 7 router like the TP-Link Archer BE6500 reduces latency spikes and packet loss that cause VPN timeouts on fiber connections.
Data Insights and Analysis
According to Surfshark’s own transparency reports, the company operates a RAM-only server infrastructure across 100+ countries, which means servers purge all data on reboot, a design that occasionally causes brief connection drops during maintenance cycles.
Downdetector data consistently shows Surfshark connection complaint spikes correlating with major OS updates, particularly Windows cumulative updates and macOS point releases, suggesting that VPN adapter drivers are a recurring friction point.
Expert Note: "Most persistent VPN connection failures in 2026 stem from IPv6 dual-stack conflicts, not from the VPN service itself. Modern operating systems aggressively prefer IPv6 routing, which bypasses the VPN tunnel and causes the client to report a false 'connection failed' state. Disabling IPv6 at the adapter level remains the single most effective advanced fix."
Frequently Asked Questions
What are the main reasons Surfshark VPN not working?
Surfshark VPN failures typically stem from outdated app versions, protocol mismatches with your network, stale DNS cache entries, or IPv6 leaking past the VPN tunnel. Switching protocols from WireGuard to OpenVPN (TCP) and restarting the Surfshark background service resolves roughly 95% of connection issues.
How do I fix Surfshark VPN stuck on connecting?
Switch your VPN protocol (try OpenVPN TCP if using WireGuard), change to an alternative server, and clear your DNS cache. On Windows, run ipconfig /flushdns and ipconfig /renew in Command Prompt as admin. These steps fix most ‘Connection Failed’ loops within minutes.
Why is Surfshark VPN not working after a Windows update?
Major OS updates often break VPN adapter drivers. Perform a clean reinstall: uninstall Surfshark, restart your device, delete remaining Surfshark folders from AppData, then download and install the latest version. Update to version 5.0+ for current Windows compatibility.
Can disabling IPv6 fix Surfshark connection issues?
Yes. Many routers broadcast IPv6 alongside IPv4, and if your device sends DNS queries over IPv6, they bypass the VPN entirely. Disabling IPv6 at the adapter level—via Network Connections > Adapter Properties on Windows—eliminates DNS leaks and stabilizes the VPN tunnel.
What should I do if Surfshark shows error code P0017?
Error P0017 indicates a virtual network adapter issue. Reinstall Surfshark completely: uninstall it, restart your device, delete remaining folders from AppData (Windows) or Application Support (Mac), then install the latest version from Surfshark’s official site.
When should I contact Surfshark support instead of troubleshooting myself?
After exhausting basic fixes (protocol changes, server switches, app reinstalls, DNS resets), contact Surfshark’s 24/7 live chat. Before reaching out, collect diagnostic logs from Settings > App Info > Send Diagnostic Logs. Also check Surfshark’s status page and Downdetector to rule out service outages.
