FAQ

Quick wins for immediate relief
Try these first before you start changing many settings. They cover most of the common causes of Surfshark blocking your internet connection.

Check your internet connection without VPN

Disable Surfshark and verify you can browse normally
If you can’t, the issue is with the base connection modem, ISP, router

Switch Surfshark server and protocol

Change server location to a nearby one
Switch protocol: try OpenVPN TCP/UDP or WireGuard recommended for speed
Reconnect and test

Disable Kill Switch briefly

If the kill switch blocks access when the VPN drops, temporarily disable it to see if the issue is the VPN itself or a broader network problem
Re-enable after testing

Reboot device and router

Simple reboot can clear stuck network states
If you’re on a router, reboot the router and then reconnect Surfshark

Check for conflicting security software

Some antivirus or firewall rules interfere with VPN tunnels
Temporarily disable security software to test re-enable after

Flush DNS cache and set DNS to trusted servers

On Windows: open Command Prompt as admin and run ipconfig /flushdns
Set DNS to a reliable option Google DNS 8.8.8.8, 8.8.4.4 or Cloudflare 1.1.1.1
In Surfshark, enable the DNS leak protection if available

Ensure you’re not on a restrictive network

Public Wi‑Fi or school/work networks may block VPNs
If possible, switch to a different network or ask the administrator about VPN access

Update Surfshark app

Check for updates and install the latest version
After updating, reconnect and test

Check for router-level VPN blocks

Some routers block VPN protocols
If you’re comfortable, enable VPN on the router or use a VPN-compatible router
Alternatively, use a router that supports VPN passthrough and configure Surfshark on the device

Deep dive: protocol, DNS, and kill switch troubleshooting
If quick wins didn’t fix the problem, a deeper look is needed. This section covers the most impactful settings to adjust. 라드민 vpn 2026년 당신이 꼭 알아야 할 모든 것 설치부터 활용 꿀팁까지

Protocols: OpenVPN vs WireGuard vs ShadowSocks

OpenVPN UDP is usually reliable and widely compatible
OpenVPN TCP can be slower but more stable on lossy networks
WireGuard offers speed, but some networks or firewalls block the protocol
Try alternating between these to find a stable option

DNS leak protection and DNS configuration

DNS leaks occur when your DNS requests bypass the VPN tunnel
Ensure DNS leak protection is enabled in Surfshark
If leaks persist, manually configure your device to use trusted DNS servers
Test for leaks using online DNS leak test tools

Kill Switch behavior and exceptions

The kill switch should prevent data leakage if the VPN disconnects
If misconfigured, it can block all traffic even when the VPN is connected
Review the kill switch rules in the Surfshark app and adjust as needed
For desktop, test with and without the kill switch to identify root cause

IPv6 considerations

Some networks and VPNs mishandle IPv6, causing connections to fail
Disable IPv6 on the device or in Surfshark settings if you’re not using it
Ensure your OS isn’t forcing IPv6 traffic that bypasses the VPN

MTU settings

A wrong MTU value can lead to fragmentation and dropped connections
Most users don’t need to manually adjust MTU, but if you’re tech-minded, test MTU in increments 1500, 1492, 1472 and see what stabilizes

Firewall and port rules

Ensure essential ports for Surfshark are open on your firewall
If you’re behind a corporate firewall, you may need specific ports UDP 1194 or 51820 are common for VPNs
Some networks deep-freeze VPN traffic; in that case, obfuscated servers or settings might help

Router and network-wide considerations
Your router can be the bottleneck or the ally. Here’s how to optimize for reliability.

Use a dedicated VPN-enabled router

A router with built-in VPN capability reduces device-level configuration
Make sure the router’s firmware is up to date
Follow Surfshark’s router setup guides for your model

Enable VPN passthrough if your router supports it

VPN passthrough allows VPN traffic to traverse NAT and firewall properly
If disabled, even legitimate VPN traffic can be blocked

Network optimization tips

Place your router closer to your device for a stronger signal
Reduce interference from other networks or devices
Switch from 2.4 GHz to 5 GHz if you’re on a crowded household network

Cellular data and roaming

If you’re on mobile data, ensure the carrier doesn’t block VPN
Some carriers aggressively throttle or block VPN protocols; switching servers or protocols can help

Advanced tips: split tunneling, obfuscated servers, and more
If you need more control and reliability on restrictive networks, these options are worth exploring.

Split tunneling

Decide which apps should go through the VPN and which should stay direct
Useful for streaming or gaming if you don’t want all traffic routed through Surfshark
Use sparingly; misconfigurations can leak IPs or cause conflicts

Obfuscated servers and protocol options

Obfuscated servers help when VPN traffic is heavily inspected
Try Surfshark’s obfuscated server options if you’re on a network that scrutinizes VPN traffic
This can fix blocking on some school or corporate networks

Always-on VPN and auto-connect rules

Set Surfshark to auto-connect on startup or when joining a new network
Reduces the chance you forget to connect after changing networks

Port-forwarding and alternative protocols

Some networks block common VPN ports
Switch to less-blocked ports or use protocols designed to circumvent strict blocks
Ensure you’re aware of potential security implications when changing ports

Monitoring and maintenance to prevent future issues
Keep Surfshark reliable by adopting a regular maintenance routine.

Regularly check for updates

App and firmware updates fix bugs and improve compatibility
Enable automatic updates where possible

Periodic DNS tests

Run DNS leak tests after major network changes or updates
If leaks appear, reconfigure DNS settings or enable DNS leak protection

Test on multiple networks

If you travel or work across networks, test Surfshark on each one
Document which server and protocol work best for each environment

Keep an eye on service status

Surfshark’s status page or social channels can alert you to outages
If there’s a known outage, it’s often a temporary problem with a quick workaround

Backup connection plan

Have a secondary VPN or a fallback DNS strategy in case Surfshark faces a widespread issue
This helps avoid being left unprotected on critical networks

Hardware considerations

If you’re using an older device, ensure its VPN clients and OS are fully updated
Outdated hardware can contribute to connection instability

Common error codes and fixes

If you see specific error codes e.g., “VPN connection failed,” “DNS leak detected”, search Surfshark’s support database for targeted fixes
Keep a quick-reference with your most common errors and remedies

Common troubleshooting checklist

Are you able to browse without Surfshark? If yes, the issue is VPN-specific
Have you tried different servers and protocols?
Is the Kill Switch enabled, and is it behaving as expected?
Is DNS leak protection on? Have you flushed DNS and set trusted DNS?
Have you rebooted devices and router recently?
Is IPv6 disabled where necessary?
Is the router VPN-ready and up-to-date?
Are you on a network that blocks VPNs? Have you tried obfuscated servers?
Have you checked for conflicting security software?
Are there any ISP or network advisories impacting VPNs?
