Surfshark vpn blocking your internet connection heres how to fix it
Section 1: Quick diagnosis — is it Surfshark or something else?
- Common causes:
- DNS leaks: your device leaks DNS requests outside the VPN tunnel.
- Firewall restrictions: school, work, or public networks block VPN traffic.
- Protocol incompatibility: certain servers or protocols don’t play well with your network.
- IP blocking or geofence: some services actively block known VPN IPs.
- Quick checks:
- Run a DNS leak test dnsleaktest.com or equivalents.
- Check if the issue happens on all apps or just one browser vs. app.
- Try a different Surfshark server. If one server works and another doesn’t, the problem is server-specific.
- Temporarily disable any antivirus/firewall and retest remember to re-enable after testing.
- Data points to consider:
- Your location, your network type home Wi‑Fi, mobile data, public Wi‑Fi
- The exact error message you see e.g., “No Internet” vs. “VPN error” vs. “Connection failed”
Section 2: Step-by-step fixes to get Surfshark back online
Step 1 — Ensure Surfshark is up to date
- Why: Outdated apps can have bugs that cause drops or leaks.
- How:
- Check for updates in your device’s app store or Surfshark’s official site.
- Install any available updates and restart the app.
Step 2 — Pick the right server and protocol
- Why: Some servers are overloaded or blocked, and some protocols work better on certain networks.
- How:
- In Surfshark, switch to a nearby server auto-connect with a preferred region.
- Try different protocols: OpenVPN UDP, OpenVPN TCP, WireGuard Surfshark’s protocol. If one protocol blocks, another may work.
- Pro tip: For streaming, WireGuard tends to provide faster speeds with good stability; for laptops behind strict firewalls, TCP OpenVPN can be more reliable.
Step 3 — Disable IPv6 and enable DNS protection
- Why: IPv6 can bypass the VPN tunnel on some setups, causing DNS leaks and unstable connections.
- How:
- On Windows/macOS, disable IPv6 for the active network interface system settings.
- In Surfshark settings, enable DNS protection and, if available, “Only use VPN DNS” or “DNS over TLS/HTTPS.”
- Verification: run a DNS leak test again to confirm DNS requests are going through Surfshark.
Step 4 — Adjust DNS settings manually
- Why: If Surfshark’s DNS isn’t being used, you’ll see leaks or failed lookups.
- How:
- Use Surfshark’s DNS servers: in settings, select the option to use Surfshark DNS or custom DNS with known secure servers like 1.1.1.1 with DNS-over-TLS if Surfshark supports it.
- On Windows: set DNS to 10.10.10.10 and 10.10.10.11 example values; use the official Surfshark DNS if provided in docs.
- On macOS/iOS/Android: configure DNS to the same values or use Surfshark’s recommended DNS.
- Validation: re-run a DNS leak test and browse to confirm the VPN’s DNS is resolving.
Step 5 — Adjust firewall or router settings
- Why: Firewalls or parental controls can block VPN protocols.
- How:
- If you’re on a corporate or school network, request an exception for Surfshark or switch to a different network.
- On your home router, ensure UDP ports required by Surfshark protocols aren’t blocked. Some routers have built-in firewall rules that block VPN traffic by default.
- Enable UPnP/NAT-PMP if you have strict NAT issues only if you’re comfortable with router settings.
- Pro tip: If you suspect port-blocking by your network, try using Stealth mode if Surfshark offers it or switch to a less-blocked protocol.
Step 6 — Disable battery or power-saving features during VPN use
- Why: On mobile devices, aggressive power-saving can interrupt VPN connections.
- How:
- Disable battery saver or adaptive brightness features while connected to Surfshark.
- Add Surfshark as a high-priority app in battery settings.
- Result: more stable VPN sessions on mobile.
Step 7 — Reinstall Surfshark if problems persist
- Why: A corrupted installation can cause consistent failures.
- How:
- Back up your settings if possible, uninstall the app, restart your device, reinstall Surfshark, log in, and test again.
- Note: If you have many saved profiles or server favorites, re-import them after reinstall if the app supports it.
Section 3 — Device-specific quick fixes
Windows
- Flush DNS: open Command Prompt as admin, run ipconfig /flushdns
- Release/renew IP: ipconfig /release then ipconfig /renew
- Check VPN adapter: ensure Surfshark virtual network adapter is installed and enabled
MacOS
- Check network permissions: ensure Surfshark has permission to create network connections
- Change VPN protocol from the app: try WireGuard if OpenVPN shows instability
- Test on different user profile if system-level restrictions exist
IOS
- Reinstall app, reset network settings if problems persist
- Try a different server region within the app
- Confirm iOS “VPN” toggle shows as connected in the Control Center
Android
- Check background data usage: ensure Surfshark isn’t restricted by data saver or battery optimization
- Clear app cache/data if you notice odd behavior
- Test with Wi‑Fi and mobile data to isolate network types
Browser Extensions
- Note that VPN browser extensions may not cover all traffic; use the full app for system-wide protection
- If extension blocks are suspected, disable the extension and test again
- Clear browser cache after enabling VPN to avoid stale DNS results
Section 4 — Real-world tips to improve reliability
- Use a wired connection when possible for desktop VPN stability
- Prefer servers in regions with fewer geolocation locks to avoid blocks
- Keep an eye on service status pages for Surfshark and your network
- Consider splitting the activity: use VPN for sensitive tasks, go direct for banking or sensitive logins only when necessary and avoid doing sensitive work on public networks
Section 5 — How to test your Surfshark connection after fixes
- Steps to verify:
- Disconnect and reconnect Surfshark after applying changes
- Run a speed test while connected to VPN
- Use dnsleaktest.com to verify DNS is through Surfshark
- Check an IP checking site to confirm your IP shows as the VPN exit node
- Try a streaming service or a geolocation check to confirm server reachability
- Metrics to track:
- Connection time latency
- Throughput download/upload speeds
- DNS leak status
- Stability over a 15–30 minute session
Section 6 — Advanced tips for power users
- Use split tunneling if available to route specific apps through Surfshark while the rest use your normal connection
- Enable automatic startup with your device so VPN protection is always on
- Create a firewall rule to block all non-VPN traffic as a fail-safe
- Regularly review which servers you use most and clear out stale cache or server lists
Section 7 — Security considerations while Surfshark is active
- Always enable Kill Switch if available to prevent leaks if VPN drops
- Use Threat Protection or equivalent features to block ads and trackers without leaking data
- Review device permissions and ensure the VPN app has only necessary rights
Section 8 — Performance comparison and what to expect
- Typical improvements:
- Stable connection after switching servers or protocols
- Lower DNS leakage risk
- Better performance on WireGuard-like protocols
- Common caveats:
- VPN may slow down your connection by 5–30% depending on distance to the server and network congestion
- Some services actively block VPN IPs; in these cases, rotating servers or using obfuscated/protocol options helps
