Quick start: 60-second sanity check

Is Mullvad VPN turned on in the client? Make sure the status shows connected when you try a test server.
Try a different Mullvad server location. Sometimes a single server can be congested or down.
Restart the Mullvad client and your device. Simple reboots fix many glitches.
Test a direct connection no VPN to confirm your baseline internet works. If the internet is down without Mullvad, the problem isn’t Mullvad.
Temporarily disable firewall or antivirus to rule out local blocks, then re-enable with exceptions for Mullvad.
Check if the Mullvad service status page if available reports outages.

Section 1 — Confirm service status and account Does total av have a vpn everything you need to know

Verify account status and payment

Ensure your Mullvad account is active and you’ve paid any required fees if applicable.
If you export a new account number or change payment status, re-authenticate in the client.

Check Mullvad server health

Some servers go offline for maintenance. Switch to a nearby server or a different country to test.
Note whether you experience identical issues across all servers or only specific ones.

Review subscription and license if applicable

Mullvad typically uses a simple account ID; verify that your account details aren’t expired or misconfigured in the client.

Look for recent outages

Check Mullvad’s official status channels or social feeds for any ongoing outages or service degradation.

Section 2 — Check device and network environment

Test on another device

If Mullvad connects on another device, the issue is likely device-specific config, firewall, or OS settings.

Check your network type

Public Wi‑Fi, corporate networks, or captive portals can block VPN traffic. Try a different network home Wi‑Fi or mobile hotspot to compare results.

Confirm date and time synchronization

Incorrect system time can cause TLS/SSL handshakes to fail during VPN setup. Ensure your clock is accurate.

Disable IPv6 temporarily

Some networks misbehave with IPv6 when using VPNs. In the Mullvad client, or your OS network settings, disable IPv6 temporarily to test.

Check for conflicting VPNs or network tools

If you have other VPNs or network-tunneling software installed, they might conflict with Mullvad. Disable or uninstall other VPNs while testing.

Section 3 — Review Mullvad client settings

Protocol selection

Mullvad supports WireGuard and OpenVPN. If one protocol fails, try the other. For many users, WireGuard offers faster, more stable performance; if issues persist, fall back to OpenVPN TCP vs UDP variant may matter.

Server and port configuration

Some servers only support certain ports. If you’re behind restrictive networks, using a specific port like 443 can help.

DNS settings

Ensure Mullvad DNS is enabled to prevent DNS leaks and test using a known public DNS e.g., 1.1.1.1 or 8.8.8.8 if needed.

Kill-switch and leaks protection

If the kill-switch is enabled, ensure it’s not blocking the actual VPN tunnel. For testing, temporarily disable the kill-switch to see if connectivity returns.

Application vs. system-wide VPN

Mullvad can run as a system-wide VPN or per-application depending on your OS. Verify the correct mode for your use case.

Wallet size of configuration files

On some devices, corrupt or partial config files can cause connection failures. Re-import or recreate your Mullvad profile.

Section 4 — DNS, leaks, and privacy checks

DNS leak testing

Use a reputable DNS leak test to confirm that DNS requests are going through Mullvad and not leaking to your ISP’s resolver.

IPv6 leaks

If IPv6 is enabled but Mullvad only supports IPv4 on a server, IPv6 traffic might leak, or cause no connection. Disable IPv6 to test.

WebRTC leaks

Some browsers leak IP information via WebRTC. Consider disabling WebRTC or using browser extensions if privacy is not the primary concern but connection stability is.

Split tunneling considerations

If you’ve enabled split tunneling, verify that the traffic you expect to route through Mullvad is actually going through the VPN tunnel.

Section 5 — Protocol and server considerations

Compare protocol performance

WireGuard generally performs well, but some networks block UDP traffic. In those cases, OpenVPN with TCP can be more reliable, albeit slower.

Server load and geography

Proximity matters for speed and stability. Always test several servers in different regions to gauge performance and reliability.

Firewall and NAT traversal

If you’re behind strict NAT, you may need to enable NAT-PMP/UPnP if your router supports it or manually configure port forwarding for the VPN port.

Latency and jitter

Run a quick ping test to a stable host like your router or a known server to gauge latency. High jitter can impact VPN performance more than raw throughput.

QoS and traffic shaping

Some networks throttle VPN traffic. If your ISP or network enforces traffic shaping, you may need to try different protocols or times of day.

Section 6 — Router and network equipment tweaks Your guide to expressvpn openvpn configuration a step by step walkthrough

Reboot and update router firmware

Outdated firmware can cause VPN traffic handling issues. Check for updates and apply them.

VPN passthrough settings

Ensure that your router allows VPN passthrough for WireGuard and OpenVPN. Some routers block VPN traffic by default.

Port forwarding and firewall rules

If you’re on a home network with strict firewall settings, ensure the VPN ports are allowed outbound and inbound if necessary.

Double-NAT scenarios

If you’re behind a double NAT common with some ISP setups, consider placing the Mullvad client on a device behind the primary NAT or enabling bridge mode on your router if supported.

DNS on router level

If your router uses its own DNS, ensure it doesn’t override Mullvad’s DNS. You may set the router to use Mullvad’s DNS or a trusted alternative.

Section 7 — Advanced troubleshooting

Check logs and error codes

Mullvad client logs can reveal specific handshake or configuration errors. Look for messages about authentication, handshake failure, or protocol mismatch.

Test with a clean profile

Create a new user profile on your device or temporarily disable third-party security software to rule out profile-specific issues.

Use a wired connection for testing

If you’re on Wi-Fi, switch to a wired connection to rule out wireless instability.

Network diagnostic tools

Use traceroute, ping, and pathping to identify where packets are dropping or getting blocked.

Consider a fresh OS or clean install as a last resort

If everything else fails, a clean OS install on a test machine can confirm whether the problem is OS-level.

Check for regional restrictions

Some countries block VPN protocols or impose restrictions that Mullvad’s servers may not bypass. If you’re in such a region, consider alternatives or contact Mullvad support for guidance.

Review security software rules

Antivirus or firewall software may block VPN tunnels. Add Mullvad to allowed apps or create explicit rules for UDP/TCP ports Mullvad uses.

Test with a different device type

If your primary device cannot connect, try Mullvad on a different OS e.g., Windows vs macOS to see if the issue is device-specific.

Direct vs. proxy mode

If you’re using Mullvad through a proxy or third-party tool, try a direct VPN connection to identify if the proxy is causing the issue.

Contact support with a detailed report

When you reach out for help, include your OS version, Mullvad version, exact error messages, server location tested, protocol used, timestamps, and any recent changes.
