Quick-start checklist: can you get back online in minutes?
- Confirm Mullvad service status: visit Mullvad’s status page or Twitter for outages.
- Check your network: try another network cell data or a different Wi‑Fi to rule out your ISP.
- Restart everything: reboot your device and router, then reopen Mullvad.
- Re-enter your credentials: refresh the account code and re-login.
- Try a different server and protocol: switch to a nearby server and use WireGuard or OpenVPN.
- Disable local security temporarily: turn off firewall or antivirus rules that might block VPN traffic.
- Verify no DNS leaks: ensure your DNS isn’t leaking and that Mullvad’s DNS servers are in use.
- Check for IPv6 issues: disable IPv6 if your network struggles with IPv6 routing.
- Run a diagnostic: capture logs from Mullvad and compare with the known-good steps below.
Common causes and how to fix them
Cause 1: Server-side issues or maintenance
- What to do: wait a few minutes and switch to a different server. Mullvad maintains multiple servers; a single node going down shouldn’t affect all users.
Cause 2: Protocol mismatch or misconfiguration
- What to do: switch protocols in the app WireGuard often performs better and is simpler to configure. If you’re on Windows, try the OpenVPN profile as a fallback.
Cause 3: DNS problems or leaks
- What to do: enable Mullvad DNS in the app settings and flush your DNS cache. On Windows, run ipconfig /flushdns; on macOS, sudo dscacheutil -flushcache; on Linux, sudo systemd-resolve –flush-caches.
Cause 4: Firewall, antivirus, or security software blocking VPN traffic
- What to do: add Mullvad to allowlist or temporarily disable security software to test connectivity. Re-enable protection after testing.
Cause 5: IPv6 traffic causing conflicts
- What to do: disable IPv6 in your device’s network settings or ensure Mullvad is configured to handle IPv6 if your network supports it.
Cause 6: ISP or network-level blocks
- What to do: try a different network, or use obfuscated/proprietary ports if your ISP blocks VPN traffic. Mullvad supports multi-port and obfuscated options in some configurations.
Cause 7: Router-level issues or double NAT
- What to do: reboot the router, ensure UPnP is off if it causes issues, or place Mullvad on a supported port while logging in through a VPN-capable router if you have one.
Platform-specific fixes
Windows
- Update Mullvad to the latest version
- Switch to WireGuard: Settings > Protocol > WireGuard
- If you’re on OpenVPN, ensure TAP drivers are installed and up-to-date
- Run Mullvad with admin privileges to avoid permission-related blocks
- Check Windows firewall: create an inbound rule for Mullvad
macOS
- Update to the latest Mullvad client
- Try WireGuard first; if you encounter issues, fallback to OpenVPN
- Verify system DNS settings align with Mullvad’s DNS
- Ensure no VPN profiles are conflicting in macOS Network settings
Linux
- Install the latest Mullvad package from the official repo
- Prefer WireGuard, which is typically faster on Linux

- Prefer WireGuard for speed and modern crypto
- Disable heavy background tasks on your device that cause congestion
- Check for bandwidth caps or throttling from your ISP
- Use a wired connection if possible to reduce interference from Wi‑Fi
DNS and privacy considerations
- Mullvad’s DNS protection helps prevent DNS leaks, but it’s worth verifying
- Use Mullvad’s DNS servers and ensure your system isn’t reverting to ISP DNS
- If you’re testing leaks, use reputable tools like dnsleaktest.com from a trusted device
