Mullvad help center

App under Windows says: failed to apply firewall rules...? #

This mostly happens with third party security and firewall software that blocks WFP from working correctly. The error will often show up in the daemon.log as : [talpid_core::winnet][ERROR] Initiate WFP transaction: The call timed out while waiting to acquire the transaction lock.

App under Linux says: failed to apply firewall rules...? #

Please make sure you are running Linux kernel version 4.8.0 or newer. Check in a terminal with "uname -a".
If it is below 4.8.0 you can upgrade with "sudo apt-get install linux-generic-hwe-16.04"
After that reboot, and then try connecting with the app again.

App says “too many simultaneous connections” when only using 1? #

This can happen if the Mullvad VPN app can't find the TAP adapter. Solution: close and, re-install the latest Mullvad VPN App. Wait 5 mins (for the connection count to clear) and then try to connect, and see if this solves the issue.

Why can’t I use the internet after closing the Mullvad app on Windows? #

Go into the "Network & Internet settings" > "Change adapter settings" and then right-click the network adapter you use to connect to the internet and select "Properties" then double-click on "Internet Protocol version 4" and set it to "Obtain DNS server address automatically" Please make sure that you are running 2020.2 or later of our Mullvad VPN app.

I get Fatal error during driver installation. Failed to identify newly added TAP adapter. #

Please make sure that you do not have any antivirus or third party firewalls that might be blocking / restricting access for installing the TAP Adapter correctly.

How do I change the app's language? #

The language is automatically determined based on your computer's language settings. You can set the environment variable MULLVAD_LOCALE to the language you wish to use of the ones we have available:

If using Linux : MULLVAD_LOCALE=en-US ./mullvad-vpn

If using Windows you set it in: System -> Advanced system settings -> Environment Variables -> and then add a System variable called MULLVAD_LOCALE with the value of en-US for English.

If using macOS from a terminal: MULLVAD_LOCALE=en-US /Applications/Mullvad\ VPN.app/Contents/MacOS/Mullvad\ VPN

Keep in mind that you will need to restart the Mullvad VPN app for it to take effect.

Why do I get a TAP driver installation issue on Windows ? #

The error message "Fatal error during driver installation : failed to create virtual adapter: error 2" or "Fatal error during driver installation. Failed to identify newly added TAP adapter." when installing the Mullvad VPN app. This is commonly caused by firewall / internet security software, for instance Comodo, please disable them and then try installing the app again.

Why do I get a lot of connection drops after starting to download or stream content on Windows? #

This is an issue with the Windows TAP drivers, and it is seen more often when using torrents, what you can do is install the older TAP driver version 9.9.2_3 and see if that resolves the issue for you, remember to reconnect after installing it.
