What causes Surfshark to block your internet connection TunnelBear VPN Browser Extension for Microsoft Edge The Complete 2026 Guide: Quick Setup, Features, Privacy, and Tips
- DNS DNS leaks and misconfigurations can reveal your real IP or break access when the VPN is on.
- Protocol mismatch: Some networks block certain VPN protocols OpenVPN, WireGuard, IKEv2, causing connection failures.
- Firewall blocks: Local or network firewalls may block VPN traffic or require exceptions.
- IP blocking: A Surfshark VPN server or IP range might be temporarily blocked by a service.
- App/driver issues: Outdated VPN apps, misconfigured network adapters, or conflicting security software.
- Device-specific quirks: Mobile data networks, corporate networks, or public Wi-Fi can behave differently with VPNs.
Initial quick fixes try these first
- Reconnect and switch servers: Pick a different Surfshark server location; sometimes a regional block or congestion is the problem.
- Change VPN protocol: In Surfshark settings, switch from Auto to WireGuard WireGuard is fast and reliable or OpenVPN if WireGuard isn’t stable.
- Toggle VPN on/off and reboot: A simple restart can reset sockets and clear stuck network states.
- Disable IPv6: Some networks have IPv6 enabled but Surfshark routes IPv4 traffic; turning off IPv6 on your device can reduce leaks and block issues.
- Allow Surfshark through firewall: Add Surfshark as an allowed app or create a firewall rule to permit VPN traffic.
- Check kill switch and network lock: If enabled, ensure it isn’t blocking all traffic unintentionally when the VPN drops.
- Temporarily disable antivirus or security suites: Some security tools interfere with VPN traffic; re-enable after test.
