What can cause Surfshark VPN to block your internet connection

Protocol blocks: some networks throttle or block specific VPN protocols OpenVPN, IKEv2, WireGuard.
DNS leaks: your device might leak DNS requests if the VPN DNS isn’t used consistently.
Kill switch misconfiguration: if it’s too aggressive, it can cut traffic even when the VPN is connected.
Router or device-level firewall: corporate or campus networks often block VPN traffic.
IP address blocking: some servers get flagged by your ISP or network as VPN traffic.
Double VPN or Multi-hop issues: misconfigured routes can cause traffic to stall.
IPv6 leaks: if your VPN doesn’t handle IPv6 properly, traffic can bypass the VPN.

Pre-checks before you change anything

Confirm Surfshark account status: ensure your subscription is active and the app is up to date.
Check device date/time: incorrect system time can cause certificate issues.
Test on another device: if it works on one device but not another, the problem is device-specific.
Test a wired connection: if you’re on Wi-Fi, try ethernet to rule out wireless interference.

Step 1: Troubleshoot quick wins that fix many blocking issues

Restart everything: close Surfshark, reboot your device, and power cycle your router.
Change server location: connect to a nearby server or a country known for reliable performance.
Switch protocol: try WireGuard for speed, OpenVPN UDP for compatibility, or OpenVPN TCP if the UDP path is blocked.
Pause firewall temporarily: if you’re on a tight corporate or school network, temporarily disable the local firewall to test.

Step 2: Verify and fix DNS and IP leaks

Use Surfshark DNS: ensure DNS is set to Surfshark in app settings.
Enable secure DNS: turn on Private DNS or DNS leak protection if available.
Test for leaks: use ipinfo.io or ipleak.net while connected to Surfshark to confirm no leaks.
Flush DNS cache: on Windows run ipconfig /flushdns, on macOS sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder; on Linux sudo systemd-resolve –flush-caches.

Step 3: Tweak kill switch and auto-connect options Troubleshooting Ey Remote Connect VPN Connection Failures Your Step by Step Guide

Enable kill switch: ensure it’s on so traffic is blocked if the VPN drops.
Test kill switch behavior: disconnect the VPN intentionally to see if traffic stops confirm it blocks leaks.
Adjust auto-connect: set auto-connect to a reliable server and ensure it reconnects after a drop.

Step 4: Modify router and device network settings

Use a compatible VPN profile on your router: flash router with a VPN-compatible firmware if your current one blocks VPNs.
Enable VPN passthrough on router: make sure IPSec, L2TP, and PPTP pass-through are allowed if you’re using those protocols.
Check MTU settings: try slightly lowering MTU to 1400-1460 on your router or device.
Disable IPv6 on VPN: some setups cause IPv6 leaks; disable IPv6 in the OS or router for testing.

Step 5: Strategic server, protocol, and feature adjustments

Try dedicated streaming servers: if streaming blocked, use Surfshark’s streaming-optimized servers.
Enable multi-hop only if needed: if latency is acceptable, multi-hop can help dodge blocks but can add latency.
Use “No Borders” or obfuscated servers: helpful on networks that throttle or detect VPNs.
Split tunneling: route only essential apps browser, chat through VPN while keeping others direct.

Step 6: Network-specific scenarios and fixes

School or work networks: these often block VPNs; use obfuscated servers and split tunneling to access not-work resources.
Public Wi-Fi: these networks are more likely to block VPNs; a robust protocol like WireGuard plus obfuscated servers helps.
ISP throttling or geoblocks: in some cases, you’ll need to change servers or use multi-hop to bypass throttling.

Common symptoms and quick verdicts

No internet after connecting: likely DNS, gateway, or kill switch misconfiguration.
DNS errors but page loads via IP: DNS leak or mis-set DNS server.
Video streaming stalls: server load or network congestion; switch to a nearby server or use a dedicated streaming server.
Slow speeds after reconnect: protocol choice, server distance, or router MTU.

Server proximity matters: aim for a server within 30-50 miles/km for best latency.
Protocol performance: WireGuard typically delivers the best speed; OpenVPN UDP balances compatibility; TCP is more stable on problematic networks but slower.
Packet loss and jitter: use a wired connection where possible; verify with ping and traceroute to Surfshark servers.

Format-friendly quick-reference checklist

Update Surfshark app to the latest version
Reboot device and router
Switch protocol WireGuard, OpenVPN UDP/TCP
Change to a closer server
Check and enable DNS protection
Verify kill switch is active
Disable IPv6 on device if leaks occur
Test with and without VPN
Try split tunneling for specific apps
Run leak tests DNS and IP
If on a router, ensure VPN passthrough and MTU are sane

Improved troubleshooting flow for different user personas

Casual streamer: focus on streaming-optimized servers, enable obfuscation, and ensure split tunneling isn’t grabbing too much traffic from the VPN.
Remote worker: ensure split tunneling is set for work apps and enable the kill switch; consider a dedicated server location near your company network.
Student on campus: use obfuscated servers and No Borders; test multiple servers to bypass campus firewall policies.

Advanced settings and optimization

Enable advanced protocol options: tweak encryption strength AES-256-GCM vs AES-128-GCM only if you know your device’s capabilities.
Use a dedicated DNS like 1.1.1.1 over VPN: sometimes public DNS works better behind VPNs but can be slower depending on location.
Regularly test for IPv6 leaks and disable IPv6 if necessary to prevent leaks in VPN configs.
Consider a backup VPN plan for critical work: if Surfshark fails often in certain locations, having a secondary provider can be a safety net.

Speed and throughput guidance

Expect up to 70-90% of baseline speed with VPN on high-speed connections when using WireGuard; lower with OpenVPN on longer routes.
Performance can vary by server load; check server load meters if available.
Streaming quality improves with nearby servers and no heavy protocol handshakes.
