Quick wins: get you back online in minutes

Pause and reconnect: Turn Mullvad off, wait 5–10 seconds, then turn it back on. Sometimes a short reset clears a stuck tunnel.
Change server or exit location: Switch to a nearby server or a different country. Some servers have temporary issues.
Temporarily disable IPv6: If your device or network uses IPv6, turning it off for Mullvad can fix leaks or tunnel issues.
Try a different protocol: OpenVPN and WireGuard are the two main Mullvad protocols. If one isn’t working, switch to the other in Settings.
Check your system clock: A skewed clock can cause certificate or crypto handshake failures. Make sure your device time is correct.
Reinstall Mullvad: If the app seems corrupt, reinstalling can fix broken configs or corrupted files.
Test a different network: If you’re on mobile data, switch to Wi‑Fi, or vice versa, to rule out a network-specific problem.
Check for firewall blocks: Some firewalls block VPN traffic. Add Mullvad as an allowed app or temporarily disable the firewall to test.

Platform-specific fixes
Windows

Run as administrator: Start Mullvad with admin privileges to ensure it can modify routing tables.
Reset network stack: Open Command Prompt as admin and run:
- netsh winsock reset
- netsh int ip reset
- ipconfig /flushdns
  Then reboot.
Disable third-party VPNs and security software: Other VPNs or AV/security suites can conflict with Mullvad.
Check service status: Make sure the Mullvad service is running in Task Manager.

MacOS

Grant full-disk access: Mullvad may need permissions to configure networking. Allow if prompted.
Add to firewall exceptions: Ensure Mullvad isn’t blocked by macOS Firewall.
Check network preferences: In System Settings > Network, verify the active service isn’t misconfigured. Re-apply the Mullvad profile if needed.
Use WireGuard or OpenVPN profile switch: Some macOS versions handle WireGuard differently; toggling can help.

Check kernel module for WireGuard: Ensure the WireGuard module is loaded modprobe wireguard.
Use 127.0.0.1 proxy if needed: Some users run Mullvad through local proxies for debugging.
Confirm DNS behavior: Mullvad DNS settings may conflict with local resolvers. Try using Mullvad DNS or a known-good DNS like 1.1.1.1.

IOS

Reinstall app: If the VPN won’t connect, reinstall Mullvad for a clean slate.
Check app permissions: Ensure Mullvad has the required network permissions in Settings.
Test with different protocol: Toggle between WireGuard and OpenVPN in the app.

Android

Check battery optimizations: Disable battery saver or allow Mullvad background activity.
Verify VPN permission: Ensure the VPN is allowed to create a VPN tunnel in Android’s security settings.
Clear app data: If the app has stored corrupted data, clearing it can help but you’ll need to re-enter credentials.

Network and router troubleshooting

Restart your router: A fresh start often clears stuck NAT and routing issues.
Check router firewall and VPN passthrough: Ensure VPN passthrough for UDP/TCP is allowed on the port Mullvad uses typically UDP 1194 for OpenVPN or the WireGuard default.
Use a wired connection: If you’re on Wi‑Fi, test with a wired connection to rule out wireless interference.
Update firmware: Router firmware updates can fix VPN compatibility issues.
Change DNS on router: Some DNS services block VPN traffic by default; try using another DNS provider.
Check ISP blocks or throttling: Some ISPs throttle VPN traffic. If you suspect this, test on a different network or mobile data.

Advanced diagnostics and logs

Enable Mullvad logs: In the app, turn on verbose or debug logs to capture connection attempts.
Read the handshake and tunnel status: Look for messages like “handshake successful” or “no route to host” to pinpoint where it fails.
Compare working vs non-working servers: If a nearby server works but another doesn’t, it’s likely server-side routing or capacity issues.
Use command-line tests for advanced users:
- ping mullvad.net to check basic connectivity
- traceroute to see where traffic gets blocked
- dig @1.1.1.1 mullvad.net to verify DNS resolution
Check for MTU issues: If packets are dropped due to MTU mismatches, lowering MTU on the tunnel interface can help.

Multi-hop or bridge setups: If you’re using complex network setups, simplify to a single-hop VPN to diagnose.
Corporate networks: Some workplaces block VPNs or force traffic through proxies; test on a personal network.
Public Wi‑Fi captive portals: Sign in to the portal first, then connect Mullvad.
Mobile carrier restrictions: Some mobile networks restrict VPN usage on certain plans; test with a different SIM or hotspot.
Firmware bugs in devices: Some devices have known VPN issues after OS updates; check the vendor’s support pages for patches or workarounds.

When to switch or contact support

If you’ve exhausted all home-tested fixes and Mullvad still fails to connect on multiple devices and networks, reach out to Mullvad support with your diagnostics log. Include:
- Your operating system and version
- Mullvad version
- The protocol you’re using WireGuard or OpenVPN
- Server you’re attempting to connect to and whether it’s a specific server or all servers
- Timestamps of failure and any error messages
If you need consistent reliability across networks, you might consider testing a backup service for short-term use while Mullvad issues are being resolved.

Statistics and data points

VPN usage trends show that a large portion of users experience connection issues due to DNS mismatches or IPv6 misconfigurations. Specifically, up to 30% of connection problems in some surveys relate to DNS leakage or IPv6 behavior when VPNs are active.
Most common fixes reduce connection failure time by up to 60% when applied early in the troubleshooting process.
The majority of Mullvad users report successful reconnects after switching protocols or servers, which is a quick-win tactic.

What should I do if Mullvad says “Handshake failed”?

Handshake failures usually point to protocol or certificate issues. Try switching protocols WireGuard vs OpenVPN, restart the app, and ensure the system clock is accurate.

Can IPv6 cause Mullvad to fail to connect?

Yes, IPv6 can confuse some tunnels. If you’re experiencing issues, disable IPv6 in your network settings for Mullvad testing, then re-enable after confirming whether it helps.

Is Mullvad compatible with all routers?

Most routers work with Mullvad via OpenVPN or WireGuard, but some consumer routers have limited VPN support. If your router doesn’t support VPNs well, connect through a device behind the router instead.

Should I use Mullvad with a DNS service?

Using Mullvad DNS can help prevent DNS leaks. Mullvad provides DNS services you can configure in the app; alternatively, set a trusted DNS like 1.1.1.1 in your device or router.

What if Mullvad works on one network but not another?

That usually points to network-specific blocks, ISP restrictions, or router misconfig. Try changing servers, adjusting DNS, or testing on mobile data. Understanding the five eyes alliance and how PureVPN can help protect your privacy

How do I check if there’s a server issue?

Try multiple servers. If several nearby servers fail, Mullvad’s backend may be experiencing trouble. Check Mullvad’s status page or social channels for updates.

Do I need to reinstall Mullvad after an OS update?

Sometimes, yes. OS updates can reset network permissions or cause config changes. A fresh reinstall can fix stubborn problems.

How can I speed up Mullvad connection if it’s slow?
