Quick checks and basics
- Confirm internet access without Mullvad: If you can’t browse the web without a VPN, fix your base connection first.
- Check Mullvad’s status: Sometimes the issue is on Mullvad’s side. Look for status pages or social updates.
- Ensure you’re logged in correctly: Double-check your Mullvad account number and the client UI shows a green connection status.
- Confirm the server selection: Try a nearby server or switch to a different country to rule out a regional issue.
- Restart everything: A quick reboot of your device and router can clear stale connections.
Common原因 and fixes
- Server overload or outages: Switch to a different server, ideally one with lower load. Mullvad’s UI sometimes shows approximate server load.
- Protocol mismatch: If your current protocol is blocked, switch to another e.g., WireGuard to OpenVPN or vice versa.
- Kill switch misconfiguration: If the kill switch is engaged and misbehaving, disable it briefly to test the connection, then re-enable with correct rules.
- DNS leaks or misrouting: Sometimes traffic leaks or routes to the wrong network path; resetting DNS can help.
- Firewall blocking VPN: Ensure Mullvad is allowed through Windows Defender Firewall, macOS Firewall, or third-party firewall rules.
- Router-level block: Some routers block VPN traffic; check if VPN passthrough is enabled for your protocol e.g., UDP ports for WireGuard.
Platform-specific troubleshooting
Windows
- Run as administrator: Launch Mullvad with elevated privileges to ensure all services start correctly.
- Reinstall Mullvad: Uninstall, reboot, then install the latest version from Mullvad’s site.
- Check network adapters: Ensure the Mullvad virtual adapter is enabled in Network Connections.
- Disable conflicting software: Some security tools block VPN traffic; temporarily disable and test.

- Gatekeeper and permissions: Ensure Mullvad has necessary permissions and is allowed to run in System Preferences > Security & Privacy.
- Check System Extensions: Verify that any required kernel extensions or network extensions are allowed.
- Test with different tunnel: Switch between WireGuard and OpenVPN if available to find a working path.
Linux
- Use the CLI: Mullvad also offers command-line usage. Check logs for error messages in journalctl or systemd status.
- Network manager integration: If you’re using NetworkManager, ensure Mullvad is added as a VPN connection with correct settings.
- DNS configuration: Review resolv.conf or systemd-resolved settings to prevent leaks.
IOS
- Cellular vs Wi-Fi: Test across both networks; some carriers block VPN traffic.
- Reinstall the app: Delete and reinstall Mullvad from the App Store.
- Permissions: Ensure Mullvad has the necessary permissions Background App Refresh, VPN toggle.
Android
- Battery optimization: Disable battery saver for Mullvad to prevent service suspension.
- App permissions: Confirm VPN service is allowed and the app isn’t restricted by data saver.
- Reinstall and update: Keep the app current; update Android if possible.
Protocol, ports, and kill switch
- Try WireGuard first: It’s usually fast and reliable; if it fails, switch to OpenVPN or another supported protocol.
- Adjust port settings: Some networks block certain ports. If you can, rotate ports within the protocol options.
- Kill switch behavior: If the kill switch triggers too aggressively, adjust its scope or temporarily disable to test connectivity.
- MTU considerations: On some networks, lowering MTU can stabilize connections. Start at 1400 and adjust.
Router and network-level issues Chrome vpn korea 한국 사용자를 위한 완벽 가이드 2026년 최신
- VPN passthrough: Ensure your router supports VPN passthrough for the chosen protocol WireGuard/OpenVPN and that it’s enabled.
- Firmware updates: Update your router’s firmware to reduce compatibility issues.
- Double NAT: If you’re behind a double NAT setup, consider placing Mullvad on a DMZ-like configuration or using a bridge mode if your hardware supports it.
- QoS and bandwidth: Higher latency or jitter can cause drops; run a speed test to verify stable bandwidth.
DNS and leaks troubleshooting
- Setup DNS manually: Point to trusted DNS resolvers e.g., 1.1.1.1 or 9.9.9.9 in the VPN or system settings.
- DNS leak tests: Use online tools to verify no DNS leakage occurs while connected to Mullvad.
- Split tunneling: If supported, configure split tunneling to route only sensitive traffic through Mullvad while other traffic uses your regular DNS.
Advanced troubleshooting and metrics
- Check logs: Mullvad client logs are a goldmine. Look for error codes and timestamps around disconnects.
- System resource check: Ensure CPU and memory aren’t maxed out; resource saturation can cause VPN dropouts.
- Time-of-day patterns: Note if disconnects happen at certain times, which could indicate ISP shaping or router overheating.
- ISP interference: Some ISPs throttle VPN traffic; using Obfsproxy-like features or switching to a different protocol or port can help.
- VPN with multiple devices: If one device works and another doesn’t, compare settings, versions, and network context.
Safety and privacy considerations
- Kill switch privacy: A robust kill switch ensures no traffic leaks when the VPN disconnects; ensure it’s properly configured.
- Logging policy awareness: Mullvad is known for strong privacy terms, but always review current policy for changes.
- Public Wi-Fi: VPN use on untrusted networks is especially important; keep your client updated and enable the kill switch.
