Quick fixes you can try right now

Restart everything

Restart Mullvad VPN client
Reboot your device
Power cycle your router unplug for 30 seconds, plug back in

Update everything

Update Mullvad client to the latest version
Update your OS
Update router firmware if you’re using a custom router

Check your account and server

Make sure your Mullvad account is active check the account status in the client
Try a different server location sometimes a given server is down or congested
Confirm you’re not exceeding any connection limits per account

Verify basic network connectivity

Ensure you have internet access without Mullvad
Disable any other VPNs or proxies running in the background
Check for a local firewall or antivirus that might block the VPN

Inspect Kill Switch and DNS settings

Enable Mullvad’s kill switch to prevent traffic leakage if the VPN drops
Try using Mullvad’s DNS servers or switch to a trusted DNS like 1.1.1.1

Change protocol and port where applicable

Switch between UDP and TCP if the client offers it
Try a different port especially if your network blocks common VPN ports

Check for IPv6 issues

Disable IPv6 in Mullvad or on your device to avoid leaks on networks that mishandle IPv6
If you must keep IPv6, ensure the VPN supports it without leaks

Temporary disable firewall rules during testing

Briefly disable firewall rules or antivirus web shields to test connectivity
Re-enable protections after testing

Check for conflicting software

Security software, sandbox apps, or parental control can interfere with VPNs
Put Mullvad on the allow/exception list if applicable

Test with a different device

See if Mullvad connects on another device on the same network
If yes, the issue is likely device-specific

Deep dive: what to check when Mullvad won’t connect

Server status and regions: Some servers experience outages. Check Mullvad’s status page for outages and maintenance windows.
Client logs: Look for error messages and timestamps. Common messages might indicate authentication failure, DNS resolution issues, or blocked ports.
Authentication method: Mullvad uses a number-letter account code. Ensure you’re entering it correctly and that the code hasn’t expired.
Network reachability: Verify that your device can reach Mullvad servers ping tests, traceroute/tracert.
DNS leakage: If DNS queries are leaking, you’ll need to adjust DNS settings to Mullvad’s DNS or a trusted alternative while connected.
Kill switch behavior: If the kill switch is too aggressive, it may block all traffic; test by disabling it briefly to see if the connection can establish.

Platform-specific troubleshooting

Windows

Run Mullvad as administrator to avoid permission issues.
Temporarily disable Windows Defender Firewall rules that could block VPN traffic, then re-enable after testing.
Disable IPv6 in the adapter settings if you suspect IPv6 leaks.

macOS

Grant Mullvad Full Disk Access under Security & Privacy if required by newer macOS versions.
Check that System Extensions or Network Extensions are allowed for Mullvad.
Use a different protocol if available OpenVPN vs WireGuard to see if the issue is protocol-specific.

Linux

Ensure the WireGuard module is loaded if using WireGuard.
Check firewall rules iptables/nftables to ensure VPN traffic isn’t blocked.
Some distros require manual config changes; follow Mullvad’s Linux guide for interface naming and config paths.

Android

Check if the VPN permission is allowed in Settings > Apps > Mullvad.
Disable battery optimization for Mullvad to prevent it from being killed in the background.
Try a different VPN protocol in the app settings.

iOS

Ensure the app has the necessary permissions and that iOS doesn’t block VPN connections due to profile restrictions.
Reinstall Mullvad if the profile or configuration is corrupt.
Test on a different network e.g., cellular data to check for carrier-level blocks.

Advanced network and firewall adjustments

Router-level VPN passthrough: Some consumer routers block VPN traffic by default. Enable VPN passthrough for VPN protocol you’re using.
Port and protocol tuning: If your network blocks standard VPN ports, you may need to switch to a less-blocked port or a different protocol.
DNS privacy settings: If you suspect DNS leaks, point your device or router to Mullvad DNS alsong with MTU tweaks if needed.
MTU considerations: A mismatched MTU can cause connection drops. Typical values are 1360-1500; test with a slightly lower MTU to avoid fragmentation.
DNS leak tests: After connecting, run a DNS leak test to verify your queries aren’t leaking to your ISP or third parties.
Split tunneling impact: If you’re using split tunneling, make sure the apps you want to protect are included in the VPN tunnel, and confirm the routes are correct.

Verifying the VPN connection and checking for leaks

Check your IP address: After connecting, visit a site like ipchicken.com or whatismyipaddress.com to confirm the IP reflects Mullvad’s server, not your local ISP.
Check DNS: Use a DNS leak test site to confirm your DNS queries go through Mullvad.
Kill switch test: Temporarily disable the VPN, then run a leak test—if you see your real IP, the kill switch isn’t active properly.
WebRTC leaks: For browsers, disable WebRTC or use a privacy-focused browser profile to prevent IP leaks through WebRTC.
Speed and latency: Run a quick speed test to compare before and after connections and gauge if the VPN is impacting performance more than expected.

Maintenance tips to prevent future issues

Schedule periodic updates: Keep Mullvad and your OS up to date, and monitor for network changes that could impact VPNs.
Regular server checks: If you rely on specific servers, rotate them or set a favorite list to auto-switch when one goes down.
Backup configurations: Save VPN profiles or configuration files you use frequently in a secure place.
Network health monitoring: Use a basic network health app to monitor jitter, latency, and packet loss, and correlate spikes with VPN issues.
Privacy hygiene: Combine Mullvad with other privacy practices like secure DNS, no-logs habits, and careful app permissions for added protection.

Frequently Asked Questions

How do I know Mullvad VPN isn’t connecting due to my device or the service?

If multiple devices on the same network struggle to connect to Mullvad, the issue is likely network-level router, ISP, or firewall. If only one device has the issue, it’s likely device-specific settings or an app conflict.

What should I do if Mullvad shows a server is down?

Switch to another server location listed in the app, or wait and retry later. Update to the latest server list when it becomes available.

Can I use Mullvad with a corporate network?

Some corporate networks block VPN traffic. If you’re on such a network, try a different network, or consult IT about VPN allowances and port usage.

How do I fix DNS leaks with Mullvad?

Set Mullvad DNS in the app or system DNS, disable WebRTC in browsers, and run a DNS leak test after connecting to verify queries are being resolved by Mullvad.

Why would Mullvad work on one device but not another?

Differences in OS settings, firewall rules, antivirus configurations, or conflicting software can cause one device to fail while another works fine. How to Reset Your ExpressVPN Password Without a Hassle: Quick Guide, Tips, and Best Practices

Is it safe to disable IPv6 while using Mullvad?

If you’re seeing IPv6 leaks or instability, disabling IPv6 can be a practical short-term fix. If you rely on IPv6 on your network, ensure Mullvad supports IPv6 properly or configure it correctly.

Can a router block Mullvad?

Yes. Some routers block VPN traffic by default. Enable VPN passthrough, configure port forwarding for your VPN protocol, or install Mullvad-compatible firmware if possible.

How can I improve Mullvad’s performance?

Try a nearby server, switch protocols, adjust MTU, disable bandwidth-heavy apps during VPN use, and ensure your internet connection itself is stable.

What should I do if Mullvad won’t connect after a Windows update?

Reinstall Mullvad, reset network settings if necessary, and re-check firewall rules. Sometimes Windows updates reset VPN permissions or network adapters.

Is there a way to test Mullvad without affecting my real traffic?
