Section: Quick Diagnostic Checklist 5–10 minutes
If Mullvad isn’t connecting, start here to identify obvious blockers.

Check your internet connection: Are other sites loading? Try a quick speed test.
Confirm Mullvad status: Are there any ongoing outages reported by Mullvad on social or status pages?
Ensure the app is up to date: Update Mullvad to the latest version for bug fixes and compatibility improvements.
Verify account status: Your Mullvad account number and payment status should be valid and not expired.
Look for firewall interference: Is Mullvad blocked by Windows Defender, macOS Firewall, or a third-party firewall?

Section: Determine Your Connection Type and Protocol
Mullvad supports several protocols, and some networks block specific ones.

Protocol options: WireGuard and OpenVPN via Mullvad client. WireGuard is faster on most networks.
If your network blocks UDP: WireGuard uses UDP by default. Switch to OpenVPN TCP if available, or adjust the port.
DNS behavior: Mullvad relies on DNS during connection. If DNS leaks or DNS blocking occur, you may see failures to connect or inconsistent IPs.
IPv6: IPv6 can cause issues on networks that are not IPv6-ready. Consider disabling IPv6 in Mullvad settings or on your device temporarily to test.

Section: Step-by-Step Troubleshooting Guide
Step 1: Reproduce the Issue

Launch Mullvad
Click Connect and note any error messages e.g., “No servers available,” “Connection failed,” “Auth failed”
Try connecting to different servers or locations e.g., a nearby country vs. a distant one
If you can connect to some servers but not others, the problem may be server-specific or geo-restriction related

Step 2: Check Local Network and Device Settings Unifi nordvpn the ultimate combo for rock solid privacy security: A complete guide to secure home networks and streaming

Restart your router and modem to refresh your network path
Disable VPN blockers on your router if you use one some routers have per-device VPN blocking or VPN passthrough settings
Verify that your device clock is accurate; time drift can cause certificate validation issues

Step 3: Modify Mullvad Client Settings

Protocol: Switch between WireGuard and OpenVPN to see which one works
Port settings: For OpenVPN, try different ports 1194, 443, 80
DNS settings: Enable “Use Mullvad DNS” or set a trusted DNS like 1.1.1.1 temporarily to test
IPv6: Disable IPv6 in Mullvad and on the device to test stability

Step 4: Test Without Other VPNs or Security Tools

If you have another VPN or a security suite, temporarily disable it to rule out conflicts
Some antivirus software blocks VPN traffic. Add Mullvad as an exception if possible

Step 5: Check Firewall Rules

On Windows: Open Windows Defender Firewall, ensure Mullvad is allowed for both private and public networks
On macOS: Check System Preferences > Security & Privacy > Firewall and allow Mullvad incoming connections
If you’re on Linux: Ensure ufw/iptables rules aren’t blocking Mullvad ports

Step 6: Verify Network-Level Blocks

Some public or workplace networks block VPN traffic. Try a different network mobile hotspot to see if the issue persists
If it works on a mobile hotspot but not on your usual network, your router or ISP might be blocking VPN protocols

Step 7: Review MTU and NAT Considerations Nordvpn vs expressvpn which vpn actually works in china: Definitive Guide to Bypassing the Great Firewall in 2026

If you’re seeing intermittent disconnects or “packet loss” symptoms, you may need to adjust MTU settings on your device or router
Common MTU values to test: 1400, 1420, or 1500 depending on your network path

Step 8: Confirm Mullvad Account and Payment Status

Make sure your Mullvad account is active and not flagged
If you’ve recently changed payment methods, confirm the account is linked correctly
Check your Mullvad receipt or account portal for any service suspension notes

Step 9: Inspect Logs for Clues

Mullvad logs can reveal why a connection fails
Look for messages about authentication, key exchange, or server handshake
If you see TLS/SSL errors, that points to certificate or DNS issues

Step 10: Reinstall as a Last Resort

Uninstall Mullvad completely
Reboot your device
Reinstall the latest Mullvad client
Reconfigure from scratch and test with a known good server

Section: Platform-Specific Tips
Windows

Run Mullvad as administrator to avoid permission issues
Disable Windows VPN auto-connect or other VPN services that might conflict
Check for Windows wireless adapter driver updates if you’re on Wi-Fi

MacOS Nordvpn on your unifi dream machine the ultimate guide for secure networking

Ensure you’ve granted Mullvad the required permissions in Security & Privacy
If you use Little Snitch or similar, ensure Mullvad isn’t blocked from network access

Android

Disable battery optimization for Mullvad, so it can run without being paused in the background
Try a different network cellular vs Wi-Fi to isolate network-specific issues

IOS

Reinstall Mullvad if you suspect a profile or certificate issue
Verify that your iPhone date/time is correct, as certificate validation can fail with wrong time

Linux

Confirm you’ve installed the latest package from Mullvad
Check your network manager’s VPN integration settings; some managers conflict with VPN clients
