What Mullvad VPN is and isn’t doing when it won’t connect
- Mullvad uses WireGuard and OpenVPN protocols. If one protocol stalls, the other might still work.
- A stuck connection usually means a local network issue, DNS hiccup, firewall blocking, or a misconfigured client.
- Symptoms you might notice: “Connecting…” stuck, authentication errors, sudden disconnections, or Mullvad shows as connected but traffic isn’t actually routed.
Key data points to keep in mind
- WireGuard is typically faster but may be blocked by some networks more aggressively than OpenVPN.
- DNS leaks can occur if the VPN tunnel isn’t properly established, leaking your real IP.
- Some ISPs employ NAT or CGNAT that complicates VPN connections but isn’t a Mullvad-specific problem.
Step-by-step quick troubleshooting guide 15-minute plan
- Check for service status and account
- Make sure your Mullvad account is active and your license or allowance is valid.
- Confirm you’re selecting a server that’s not overloaded. Mullvad’s client shows server load; pick a lower-load option when possible.
- Verify your app version and updates
- Update Mullvad to the latest version on your device.
- If you recently updated and started having issues, consider rolling back to a prior version temporarily but aim to stay current for security.
- Switch protocols and servers
- Try WireGuard first; if it fails, switch to OpenVPN UDP or TCP and test both.
- Change to a nearby server. Distance can affect latency and stability.
- Restart and reset
- Restart Mullvad app, then reboot your device.
- Power cycle your router/modem. Wait 2–3 minutes, then try again.
- Check local network and firewall rules
- Ensure your firewall or antivirus isn’t blocking Mullvad. Temporarily disable them to test connectivity.
- If you’re on a corporate or school network, VPNs may be blocked. Try a different network or use a portable hotspot.
- DNS and leaks test
- After connecting, perform a DNS leak test e.g., search “DNS leak test” and run one. If your real DNS shows, reconfigure Mullvad DNS settings or use a provided DNS within Mullvad.
- Enable DNS over TLS/DoT if available in the app settings.
- Check for IPv6 issues
- Some networks have flaky IPv6 support. Disable IPv6 in your device or in Mullvad settings to see if that stabilizes the connection.
- Confirm correct login method
- Mullvad uses account numbers instead of username/password. Ensure you’ve entered the correct account number and/or the correct token if your setup requires it.
- Check system time and date
- VPN certificates can fail if your system clock is off. Sync time with the internet time server and retry.
- Review MTU settings
- If you’re on a constrained network, a incorrect MTU can cause fragmentation and drop VPN packets. Try a smaller MTU value e.g., 1400 in the Mullvad app if the option exists.
Platform-specific troubleshooting tips
Windows
- Run as administrator: Right-click Mullvad and choose “Run as administrator.”
- Disable IPv6 as a test: Control Panel > Network and Internet > Network Connections > right-click your active adapter > Properties > uncheck Internet Protocol Version 6 TCP/IPv6, then reconnect.
- Check Windows firewall: Temporarily allow Mullvad through the firewall and ensure it’s not blocked by security software.
macOS - Allow VPN in Security & Privacy: System Preferences > Security & Privacy > Privacy tab > Full Disk Access if required and allow Mullvad.
- Check network locations: System Preferences > Network > Advanced > Proxies, ensure no proxies override traffic for Mullvad.
Linux - Use the terminal to restart services: systemctl –user restart mullvad-daemon.service or appropriate service for your distro.
- Confirm kernel module support: Ensure WireGuard is loaded: modprobe wireguard; check with lsmod | grep wireguard.
Android - Try a different network: Switch to mobile data if you’re on Wi-Fi and observe the result.
- Check battery saver settings: Some devices throttle background apps; disable battery optimization for Mullvad.
iOS - Reinstall if issues persist: Delete Mullvad, reinstall from App Store.
- Ensure VPN is allowed in settings: Settings > General > VPN & Device Management, ensure toggles are correct.
Common errors and how to fix them
- “Connecting…” stuck
- Switch servers, try WireGuard then OpenVPN, restart app, reboot device.
- “Authentication failed”
- Double-check your account number vs token, re-enter credentials, ensure you’re not mixing accounts on multiple devices.
- “No internet after connect”
- Disable IPv6, test a different server, verify DNS settings, ensure the VPN is the default gateway.
Advanced troubleshooting and diagnostics
- Check logs for clues
- Mullvad has diagnostic logs in the app. Look for errors related to key exchange, handshake, or DNS failures.
- Test with a different protocol stack
- Compare performance and stability between WireGuard and OpenVPN UDP/TCP to identify a protocol-specific block.
- Use manual DNS configuration
- In Mullvad, set custom DNS servers or enable their built-in DNS to prevent leaks and improve resolution reliability.
- Verify no routing conflicts
- Ensure there are no conflicting routing rules on your device that bypass the VPN tunnel.
When to contact support
- If you’ve followed all steps and Mullvad still won’t connect, collect the relevant data:
- Device OS and version, Mullvad version, server location, protocol used, error messages, and screenshots.
- Contact Mullvad support with your data. They can inspect server-side logs and provide server-specific guidance.
Real-world tips to improve reliability and speed
- Use preferred servers during peak hours to avoid congestion.
- Enable split tunneling if you only need VPN on certain apps to reduce load on the tunnel.
- Keep your router firmware up to date to ensure compatibility with VPN protocols.
- Consider a wired connection for desktop devices to reduce interference and packet loss.
Security considerations you shouldn’t overlook
- Always verify you’re connected to Mullvad’s official server network; beware phishing apps that mimic VPNs.
- Regularly update your VPN client and underlying OS for the latest security patches.
- Use Kill Switch and DNS leak protection features to prevent exposure during drops.
- Be mindful of logging policies and data collection; Mullvad is known for its strong privacy stance, but always review current terms.
Industry data and authority
- Global VPN market size and growth: The VPN market is projected to reach over $70 billion in the next few years, with privacy concerns driving adoption.
- WireGuard adoption: WireGuard has become the de facto standard for modern VPNs due to simplicity and speed, while OpenVPN remains widely used for compatibility.
- DNS leakage concerns remain a top reason users distrust VPNs; enabling DNS protections reduces exposure risk.
