Body
Quick diagnosis: is Mullvad actually connected or blocked?
- Check the Mullvad app status: Look for a green connected indicator. If you see “VPN off” or similar, the issue is at the app or service level.
- Verify on the OS level: Your IP address should show as a Mullvad exit location when connected. If not, the tunnel isn’t established.
- Ping test: Use a simple ping or visit a geo-restricted site to see if traffic is going through Mullvad.
Common causes
- Incorrect account number or missing payment in Mullvad account
- Server overload or regional blocks on the chosen exit server
- Local firewall, antivirus, or router blocking VPN traffic
- DNS leaks or misconfigured DNS settings
- IPv6 traffic trying to bypass the VPN
- Outdated Mullvad app or client configuration
Step-by-step: basic fixes you can try now
- Restart everything
- Close Mullvad, quit the app, restart your device, router, and then reopen Mullvad.
- Try a different Mullvad server location after reboot.
- Confirm account and payment status
- Double-check your Mullvad account number 16-digit code and ensure it’s active.
- If you recently paid, allow a few minutes for the system to reflect changes.
- Update the app and system
- Install the latest Mullvad client on your device.
- Update your operating system to the latest stable version.
- Reboot after updates.
- Check server status and switch locations
- Some servers may be overloaded or temporarily blocked.
- Switch to a nearby server or a different country to test connectivity.
- Tweak protocol and port settings
- Try switching protocols WireGuard is Mullvad’s default, but you can test OpenVPN if available and switch ports if the option exists.
- Enable or disable obfuscation if you’re in a restricted network.
- Disable conflicting software
- Temporarily disable firewall, antivirus, or security software to test connectivity.
- If you’re on Windows, ensure Mullvad isn’t blocked by Windows Defender Firewall rules.
- On macOS, check System Preferences > Security & Privacy > Firewall.
- DNS checks and leaks
- Set Mullvad DNS in-app if available.
- Flush DNS on your device instructions vary by OS.
- If DNS leaks persist, try a different DNS provider e.g., 1.1.1.1 or 9.9.9.9 temporarily.
- IPv6 handling
- Disable IPv6 in your network settings to force IPv4, which can stabilize VPN connections in some networks.
- Re-enable IPv6 after testing if needed.
- Router-level adjustments
- Reboot the router and ensure it isn’t filtering VPN traffic.
- If your router supports VPN pass-through, confirm it’s enabled for the protocol you’re using.
- Check for firmware updates on your router.
- Check for traffic shaping or ISP blocks
- Some ISPs throttle VPN traffic. Try a different network mobile hotspot to confirm.
- If you’re on a school or corporate network, VPN traffic can be restricted.
- Reinstall Mullvad
- Uninstall Mullvad completely, then reinstall the latest version.
- Import your account again if needed, and verify the 16-digit code.

Advanced troubleshooting for power users
Network capture basics for tech-savvy readers
- Run a packet capture while attempting to connect to Mullvad to identify where the handshake fails.
- Look for TLS/DTLS handshake messages and the successful handshake with the Mullvad exit node.
Check system logs and Mullvad logs
- On Windows, open Event Viewer and filter for Mullvad-related events.
- On macOS, use Console.app to find Mullvad client logs.
- Mullvad logs can reveal authentication failures, protocol negotiation issues, or blocked ports.
Firewall and router logs
- Review firewall logs for blocked UDP/TCP ports used by Mullvad.
- Ensure outbound traffic to Mullvad servers isn’t being blocked by your network policy.
DNS and IPv6 torture tests
- Run a DNS check by visiting dnsleaktest.com while connected to Mullvad.
- If leaks show, adjust DNS settings or disable IPv6 temporarily.
When to switch off Mullvad and test baseline connectivity
- If you have no VPN at all, test baseline internet connectivity without Mullvad to rule out ISP issues.
- If another VPN connects but Mullvad doesn’t, the problem is likely Mullvad-specific account, protocol, or server pairing.
Performance and privacy considerations
- Mullvad is known for strong privacy practices, including no personal data logging and straightforward privacy policy. Keep in mind that VPN performance can vary by location, server load, and your base internet speed.
- Typical Mullvad connection speeds vary by server distance and congestion. In many cases, you’ll see 60–85% of your base speed on nearby servers, with longer distances seeing more variance.
- Use the Mullvad speed test feature if available to gauge real-time performance and adjust server choice accordingly.
Network-specific tips
Windows 10/11
- Run Mullvad as Administrator to ensure all network layers initialize properly.
- Ensure SmartScreen or Defender isn’t blocking the app’s components.
- Check that “Automatically detect settings” is turned off in VPN-related proxy settings if you’re not using a proxy.
macOS
- Allow Mullvad through Firewall in System Preferences.
- Ensure you’re not using a VPN profile conflict that routes traffic elsewhere.
Linux
- Verify you have the latest kernel and that your NetworkManager integration is up to date.
- Use terminal commands to connect and verify for example, mullvad relay status and wg show for WireGuard.
iOS and Android
- Check battery optimization settings that might kill the app in the background.
- Re-install the app if background connectivity seems flaky.
- On Android, ensure VPN permission is granted and the app isn’t blocked by battery optimizations.
Security and privacy reminder
- Always verify you’re connected to Mullvad by cross-checking your public IP and location via trusted sites.
- Avoid reusing old server configurations; fresh server data helps avoid stale routes.
- Regularly update the app to mitigate protocol or security flaws.
