• Restart everything: close Mullvad, reboot your device, restart your router.
• Update everything: ensure Mullvad app and your device OS are up to date.
• Try a different server: switch to a different Mullvad server or location.
• Switch protocols: try WireGuard, OpenVPN TCP/UDP, or other protocol options Mullvad supports.
• Disable conflicting software: temporarily disable antivirus, firewall, or VPN blockers.
• Check for IPv6 issues: disable IPv6 on your device or in Mullvad settings if you suspect IPv6 leaks.
• Verify DNS settings: set Mullvad DNS or use a trusted DNS like 1.1.1.1 temporarily.
• Test on another network: try a different Wi‑Fi or mobile hotspot to rule out router problems.
• Reinstall if needed: uninstall Mullvad, clear leftover configs, then reinstall.

Section: Platform-specific troubleshooting Does nordvpn report illegal activity the truth you need to know

Windows

• Basic steps: Run Mullvad as Administrator, ensure Windows Defender or firewall isn’t blocking the app, and confirm the VPN tunnel is created.
• Network adapters: open Network & Internet settings > Change adapter options and look for Mullvad TAP or WireGuard adapters; disable conflicting adapters.
• DNS leak check: visit a site like dnsleaktest.com to ensure queries aren’t leaking outside the VPN.
• Startup and services: ensure the Mullvad service is running in Services services.msc and set to Automatic.
• Proxies: remove any manual proxy settings unless Mullvad requires them for a specific network.

MacOS

• Gatekeeper and security: confirm Mullvad is allowed in Security & Privacy preferences.
• Kernel extensions: if prompted to allow a kernel extension, approve it, then reboot.
• Spotlight indexing: a temporarily heavy macOS task can slow VPN startup; give it a minute and retry.
• Network preferences: ensure Mullvad’s virtual NIC appears in Network settings and is prioritized over other adapters.

Linux

• Package and permissions: install from the official repository, ensure you have root access for network changes.
• Systemd service: check systemd status for Mullvad if you’re using a headless setup.
• DNS and resolvconf: ensure /etc/resolv.conf is writable or use systemd-resolved as appropriate.
• Firewall rules: make sure ufw/iptables aren’t blocking the VPN ports WireGuard uses 51820 UDP by default; OpenVPN uses 1194 UDP/TCP, etc..
• Route/table checks: verify that traffic is going through the VPN tunnel with ip route and ip rule.

IOS

• Background refresh: enable Mullvad in Background App Refresh.
• Protocol choice: if WireGuard isn’t connecting, try OpenVPN profile if supported.
• Battery saver: disable Low Power Mode while connecting, as it can throttle background tasks.
• Permissions: ensure Mullvad has necessary permissions for network and location services if required by the app.

• Background data: ensure Mullvad is allowed to run in the background.
• Battery optimization: turn off battery optimization for the Mullvad app.
• Protocol toggles: experiment with WireGuard and OpenVPN profiles.
• Per-app VPN: if you’re using per-app VPN, confirm you’ve granted access to the apps you want protected.

Section: Network and DNS troubleshooting

• DNS consistency: switch to Mullvad DNS or a trusted public DNS while connected to reduce leaks.
• IPv6 handling: disable IPv6 on devices if you’re seeing IPv6 leak warnings or inconsistent connectivity.
• Router checks: ensure you aren’t running double NAT, which can disrupt VPN connections. If possible, enable bridge mode or place the router in a passthrough state for the Mullvad device.
• Port and protocol compatibility: some networks block certain ports; switching to a different protocol or port can help e.g., WireGuard uses UDP; OpenVPN can use TCP/UDP.

Section: Protocol and server selection tips

• Start with WireGuard: it’s typically faster and more reliable on most networks.
• Try OpenVPN as fallback: some networks have strict UDP restrictions; OpenVPN over TCP can be more stable in those cases.
• Server location proximity: pick servers physically closer to you for lower latency; if you’re trying to bypass geo-blocks, you may need a location in a specific country.
• Server load: avoid servers with high load; Mullvad shows server load indicators in the app.
• Multi-hop or obfuscated modes: if you’re in a restrictive network school, workplace, country with VPN blocks, use Mullvad’s obfuscation or multi-hop features if you need an extra layer of concealment.

Section: Router and network-level checks

• VPN on router: if you’re using Mullvad on a router, ensure the router supports the needed VPN protocol, and the firmware is up to date.
• Port forwarding: some network configurations require port forwarding to stabilize a VPN connection; consult your router manual.
• DNS on router: you can configure the router to use Mullvad DNS or a neutral DNS to prevent leaks.
• Split tunneling: if your router supports it, consider split tunneling to route only certain traffic through Mullvad to avoid congestion.

Section: Advanced troubleshooting logs and diagnostics

• Collect logs: enable verbose logging in Mullvad to capture connection attempts, errors, and disconnections.
• Check system logs: on Windows, look in Event Viewer; on macOS/Linux, use Console or journalctl for relevant Mullvad entries.
• Test with a fresh profile: create a new Mullvad profile/account and attempt a connection to rule out account-specific issues.
• Compare networks: test connections on two different networks home, mobile hotspot to identify network-specific blocks.
• Verify TLS/SSL: in some restricted environments, TLS inspection by network admins can interfere with VPN connections; if you suspect this, contact your network administrator or switch networks.

• Issue: Mullvad won’t start
  Fix: reinstall, update the app, and check that the service is enabled. Run as administrator if on Windows. Verify the kernel module or TAP device is installed correctly.
• Issue: Connection drops after a few minutes
  Fix: switch servers, change protocols, or disable firewall rules that trigger after idle periods. Check for energy-saving settings that suspend network activity.
• Issue: DNS leaks detected
  Fix: set Mullvad DNS in the app and on device settings; enable DNS leak protection if available.
• Issue: Slow speeds
  Fix: switch to WireGuard, pick the closest server, and ensure you aren’t throttled by your ISP. Check for background downloads or other apps hogging bandwidth.
• Issue: VPN blocked by network
  Fix: enable obfuscated/protocol scrambling if Mullvad offers it, or use a different port/protocol. Try a server in a country with fewer blocks.

Section: Performance and reliability best practices

• Regular updates: keep Mullvad and your OS updated to benefit from security fixes and performance improvements.
• Automatic reconnect: enable automatic reconnect on VPN drop to minimize downtime.
• Kill switch: enable Mullvad’s kill switch to prevent data leaks if the VPN disconnects.
• Obfuscation: use obfuscated servers if you’re on restrictive networks to bypass deep packet inspection.
• Multi-hop: for sensitive uses, enable multi-hop routing to add an extra layer of security.

Section: Security considerations

• Data privacy: Mullvad is known for a strong no-logs policy; ensure you understand what data is collected during troubleshooting and when seeking support.
• Endpoint security: keep devices free of malware; VPN performance can be impacted by other software hijacking network traffic.
• Trust signals: if you notice unusual behavior unexpected IPs, inconsistent logs, pause usage and contact Mullvad support.

• Can you connect to Mullvad without errors? Yes/No
• Is your IP showing as Mullvad’s server location? Yes/No
• Are DNS queries resolving through Mullvad DNS? Yes/No
• Is IPv6 disabled or properly handled? Yes/No
