Troubleshooting VPN connection errors
There are a few common causes for connection errors, such as error 1009, 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 dedicated firewall or how to turn it off please refer to its manual, contact the manufacturer or your ISP.
• Another VPN/Proxy is running when you try to connect. In this case, disable the other VPN/Proxy solution.
• You are trying to connect from 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.
IMPORTANT! Depending on the device you’re currently using, the following ports have to be open:
• Windows: 1194 UDP
• Mac: 500 UDP & 4500 UDP
