Quick diagnosis

Is Mullvad failing on one device or all devices? If one device works, the problem is likely device-specific. If none work, the issue is network or service-related.
Are you able to connect to other VPNs? If yes, Mullvad specifically may be blocked or misconfigured.
Do you see error codes? Note them. They point to network issues, authentication, or DNS problems.
Is your internet connection stable? A flaky connection will kill VPN sessions.

Common causes of Mullvad not connecting 路由器翻墙：全面指南与实用技巧，提升上网自由度与安全性

DNS issues: DNS leaks or incorrect DNS can prevent Mullvad from establishing a tunnel.
Firewall or antivirus interference: Security software may block Mullvad’s traffic.
Router/network blocks: Some networks block VPN traffic or specific ports.
Outdated client: Running an old Mullvad client can cause compatibility problems.
MTU misconfiguration: Incorrect MTU values can cause packet fragmentation and connect failures.
Incorrect server or account settings: Wrong server address, port, or account status.
Kill switch or leak protection: Aggressive kill switches can cut connections if traffic leaks occur.
ISP blocking or throttling: Some ISPs detect and disrupt VPN traffic.
VPN tunneling protocol mismatch: Mullvad supports multiple protocols; a misconfiguration can cause failure.

Device-agnostic fixes fast wins

Restart Mullvad client and device: a simple reboot often fixes temporary glitches.
Switch servers: try a nearby or different server to rule out a server-side issue.
Change protocol: switch between WireGuard and OpenVPN if available.
Check for app updates: ensure Mullvad is up-to-date.
Confirm account status: verify your Mullvad account is active and your payment if applicable is valid.
Disable firewall/antivirus momentarily: to test if they’re blocking Mullvad traffic don’t leave them disabled long.
Reinstall Mullvad: a clean install can fix corrupted configuration files.

Network and router tweaks

Check router firmware: outdated firmware can cause VPN incompatibilities.
Enable port forwarding or UPnP as needed: some ISPs block ports Mullvad uses.
MTU settings: try lowering MTU from the default e.g., from 1500 to 1420 or 1400.
DNS settings: switch to a reliable DNS like 1.1.1.1 and 8.8.8.8 Google DNS or use Mullvad’s DNS if provided.
DNS over TLS/HTTPS: ensure no conflicting DNS settings on the router.
Use a different DNS server on the device: bypass router DNS with manual DNS entries.
Check for DPI or traffic shaping: some networks use Deep Packet Inspection to throttle VPNs.

Client-side troubleshooting by platform

Windows

Run as administrator: right-click Mullvad and choose Run as administrator.
Check Windows Firewall: allow Mullvad through firewall or temporarily disable firewall to test.
Check network adapters: ensure the VPN adapter shows as connected.
Reset network settings: run netsh winsock reset and ipconfig /release then /renew.
Update network drivers: ensure your NIC drivers are current.
Verify service mode: Mullvad can run as a service; ensure the service is active.

Allow system prompts: macOS may block apps from loading network extensions.
Reinstall kernel extensions if prompted: follow Mullvad’s instructions for macOS.
Check Firewall & Privacy: grant necessary permissions for Mullvad.
Try different protocol settings in preferences: toggling between WireGuard and OpenVPN can help.
Terminal tests: use ifconfig and route -n get default to verify routing.

Linux

Install the latest package: use your distro’s package manager to install Mullvad.
Check permissions: ensure the user can run tun devices often requires sudo.
Service management: systemctl status mullvad, systemctl restart mullvad.
Verify kernel modules: make sure tun/tap is loaded modprobe tun.
NetworkManager integration: if using NetworkManager, ensure Mullvad’s plugin is enabled.

IOS

Check iOS VPN toggle: ensure the VPN toggle is off, then on again.
Reinstall the app: delete and reinstall Mullvad from the App Store.
OS permissions: confirm Mullvad has permission to configure VPN settings.
Battery and power-saving settings: disable aggressive power saving that may disrupt VPN.

Android

Clear cache and storage: in App settings, clear Mullvad data.
Check device security: some antivirus apps on Android block VPNs.
Try a different server and protocol: WireGuard vs OpenVPN.
Check battery optimization: disable battery saver for Mullvad.
Reinstall and grant permissions: re-install and allow VPN configuration requests.

Advanced checks logs and diagnostics

Enable detailed logs: turn on verbose logging in Mullvad and capture logs.
Look for common error messages: authentication failures, DNS errors, or tunnel establishment failures.
Check system logs: on Windows Event Viewer, macOS Console, or Linux journalctl.
Test connections with different networks: try mobile data, a different Wi-Fi, or a wired connection.
Check for IP leaks: use a service like ipleak.net to confirm no leaks during testing.
Verify tunnels: compare WireGuard and OpenVPN tunnel results and use the one that stabilizes quickly.

MTU and DNS deep dive 翻墙方法：完整指南、实用技巧与风险分析，涵盖VPN选择、隐私保护与常见误区

MTU basics: a mismatch can cause fragment drops and failed connections.
How to test MTU: use ping with the -f -l options to find the largest packet size that works.
Recommended safe MTU: many users find 1420–1460 works; adjust gradually and test.
DNS considerations: a broken DNS setup can prevent initial handshake; set a reliable DNS in the device or Mullvad client.

Kill switch and leak protection

Understanding kill switch: it blocks all traffic if VPN drops to prevent leaks.
If you’re testing, temporarily disable kill switch to confirm if it’s the cause.
If you rely on leak protection, ensure it’s not misconfigured to disconnect on normal network changes.

Protocol-specific tips

WireGuard: typically fastest and simplest; ensure the correct port and allowed IPs are set.
OpenVPN: may be more reliable on restrictive networks; try TCP vs UDP variants.
Mixed environments: some networks play nicer with one protocol over another; experiment to see what sticks.

Common edge cases

Corporate networks: captive portals or proxies can block VPNs; connect to a trusted network first.
Public Wi-Fi: some networks require login; complete the login flow before connecting.
Router-level VPN: conflicts between router VPN and Mullvad client; disable router VPN when testing.

Best practices and prevention

Keep software updated: always run the latest Mullvad client and OS updates.
Use a reliable backup server list: rotate servers to avoid overloading a single server.
Regularly review account status: ensure payment and account details are current.
Maintain a clean network environment: avoid conflicting security software or VPNs.
