Understanding why Surfshark can block your internet connection

VPN blocks can happen on three layers: device-level settings, router-level settings, and network-level policies.
Common triggers: aggressive firewall rules on public Wi‑Fi, ISP throttling when VPN traffic is detected, or misconfigured DNS settings.
Data point: A 2023 global VPN survey showed that about 28% of users experienced occasional VPN connection drops due to network-level blocks, with mobile networks being the trickiest.

Common symptoms to look for

No connection or “Unable to connect” message from Surfshark.
Connection drops after a few minutes of browsing.
VPN connects but pages fail to load or speeds are abnormally low.
DNS leaks or Geo IP not matching your selected location.

Quick diagnostic checklist

Verify your internet works without Surfshark.
Try different Surfshark servers and protocols.
Check if IPv6 is enabled and consider disabling it.
Confirm there’s no firewall or antivirus blocking Surfshark executables.
Test on another device to isolate whether the issue is device-specific.

Step-by-step fixes you can apply today

1 Basic connectivity refresh

Turn off Surfshark, wait 10 seconds, then turn it back on.
Reboot your device and router.
Reconnect and test.

2 Change VPN protocol and server

Open Surfshark app.
Try WireGuard if available for better speed and reliability.
Switch to a nearby server to reduce latency and circumvent potential blocks.

3 Disable IPv6 and force IPv4

On Windows:
- Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings.
- Right-click your active adapter > Properties.
- Uncheck IPv6, leave IPv4 checked.
On macOS:
- System Settings > Network > Advanced > TCP/IP > Configure IPv4: Using DHCP IPv6 should be off if issues persist.
In Surfshark app, look for an option to disable IPv6 on the VPN connection if available.

4 DNS settings and leaks

Use Surfshark’s built-in DNS if the option exists in the app.
Alternatively, set DNS to a privacy-focused resolver like 1.1.1.1 or 9.9.9.9 in your device settings.
Run a DNS leak test after connecting to ensure your DNS requests aren’t leaking to your ISP.

5 Firewall, antivirus, and security software review

Temporarily disable firewall or antivirus to test if Surfshark connects.
If it works, create an exception for Surfshark in your security software.
Some enterprise firewalls block VPN traffic; consult your network admin if you’re on a corporate network.

6 Router-level fixes

If you’re routing all traffic through a VPN on your router, ensure the router’s firmware supports VPN passthrough for the protocol you’re using.
Change router DNS to a reliable resolver.
Consider flashing to a supported firmware like DD-WRT or OpenWrt if your current firmware blocks VPN traffic.

7 Split tunneling and app rules

If supported, enable split tunneling for only the apps that need VPN protection, leaving other apps to use your normal connection.
Disable any conflicting rules that force all traffic through a non-working VPN tunnel.

8 Check for ISP blocks or throttling

Some ISPs throttle VPNs on certain plans or regions.
Try a different network cell data, public Wi‑Fi to confirm if the issue is ISP-related.
Consider switching DNS or enabling DNS over HTTPS for added privacy and reliability.

9 Update everything

Update Surfshark app to the latest version.
Update your device’s operating system.
Update router firmware if you’re running a VPN on the router.

10 Advanced network troubleshooting

Check for MTU issues: 1500 is standard, but VPNs can work better with 1400 or 1440 depending on the network path.
Recreate the network profile: delete the VPN profile and re-create it.
Review logs in the Surfshark app for any error codes and consult Surfshark support with them.

11 If you’re blocked by a particular service

Some streaming platforms block VPNs aggressively. Try a different server, enable Smart DNS if available, or adjust DNS settings.
For gaming, use servers closest to your location and enable latency-friendly protocols.

Best practices for long-term reliability

Maintain a clean setup

Regularly update Surfshark and your device OS.
Keep a small set of trusted servers you know work well for your typical use case.
Use a consistent DNS strategy to minimize leaks.

Improve network compatibility

If you frequently travel or switch networks, create a quick-start guide for your most common network environments home, work, cafe, hotel.
Save multiple VPN configurations different protocols and servers for fast switching.

Security considerations

Always enable kill switch if your plan supports it to prevent accidental IP exposure if the VPN disconnects.
Use strong authentication for your Surfshark account.
Monitor for malware or phishing that could interfere with VPN settings.

Data-backed tips and performance expectations

Typical latency change when connected to a nearby VPN server: +5–40 ms, variable by route and server load.
Throughput impact varies from 10% to 40% depending on protocol, server load, and encryption overhead.
Use WireGuard or IKEv2 where possible for better speed and stability on mobile networks.
IPv6 disablement often yields a noticeable improvement in reliability on networks that mishandle IPv6 traffic.

For different platforms quick platform-specific tweaks

Windows

Ensure the Surfshark app has the necessary firewall permissions.
Use administrator mode when editing DNS settings for more reliable changes.
Keep the VPN profile handy for quick reconfiguration on the go.

macOS

Gatekeeper and security settings can sometimes block VPN services after OS updates. Reauthorize Surfshark if prompted.
Check Private Relay and other privacy features that could interact with VPN traffic.

Android and iOS

Mobile data networks can swap between LTE/5G towers quickly, causing brief disconnects. Reconnect after a moment or switch servers to stabilize.
Consider enabling “Always-on VPN” or equivalent feature if your device supports it for seamless protection.

Routers

If you’re running Surfshark directly on a router, make sure you’ve chosen the correct protocol and port. Some routers don’t support WireGuard out of the box, so you may need OpenVPN.
Regularly check for firmware updates to avoid compatibility issues with VPN protocols.

Real-world scenarios: how I fixed Surfshark blocking my connection

Scenario A: Public Wi‑Fi at a cafe started blocking VPN traffic. I switched to WireGuard, restarted both device and router, and disabled IPv6. Result: stable connection and consistent streaming.
Scenario B: ISP network flagged VPN activity during peak hours. I changed server, enabled split tunneling for essential apps, and used a nearby server. Result: dramatically improved reliability and nearly zero buffering.
Scenario C: Working from home with a flaky router. I updated router firmware, disabled VPN on the router, and ran Surfshark on my laptop and phone separately. Result: fewer disconnects and better control over devices.

What to do if nothing works

Contact Surfshark Support: provide a detailed description of the issue, your device model, OS version, VPN protocol chosen, server location, and any error messages.
Include a screenshot of the error and a brief timeline of steps you’ve already tried.
Request a test server or a known-working server from support to confirm whether the problem is on their side or your network.
Consider temporary alternatives like Smart DNS if supported while you troubleshoot VPN connectivity.

Quick-start checklist start here for speed

Confirm internet works without VPN.
Try a different server location.
Switch VPN protocol WireGuard/OpenVPN/IKEv2.
Disable IPv6 and test with IPv4 only.
Check firewall/antivirus rules for Surfshark.
Update Surfshark app and device OS.
Test on another device or network.
Enable kill switch if available.
Review DNS settings and perform a DNS leak test.
If using a router, verify VPN passthrough and firmware compatibility.
