Fix Bitdefender VPN errors 2, 4, 9, 12 and more on Windows, Mac, Android, iOS

Here you’ll find quick-fix solutions to common Bitdefender VPN connection errors on Windows, macOS, Android, iOS, or iPadOS. These are some of the error messages you may encounter when connecting to Bitdefender VPN: 

An error occurred while trying to connect. Error code: 2 | Error code: 4 | Error code: 9 | Error code: 10 | Error code: 12 | Error code: 99 | Error code 182 | Failed to get server list, please try again later. | 

There are a few general causes for connection errors encountered by Bitdefender VPN:

    • You are not connected to the Internet and can’t access the Internet via Wi-Fi or Ethernet cable. Make sure you have Internet access before using Bitdefender VPN.
    • A strictly configured firewall is preventing VPN connectivity (e.g. 3rd party firewall software, router’s built-in firewall). If you are not sure if your router comes with a dedicated firewall or how to turn it off please refer to its manual, contact the manufacturer, or your ISP.
    • Another VPN or Proxy is running when you try to connect. In this case, disable the other VPN/Proxy solution.
    • You’re on a public Wi-Fi such as work, school, airport, etc. which may have blocked the ports required by Bitdefender VPN. You need to contact the network administrator to try and change their firewall settings.
    • The port used for the VPN connection is closed. Depending on the device you’re currently using, the port 443 UDP must be open.
