My Bitdefender VPN Stopped Working A Few Days Ago And Will Not Connect Now

Hello @Joseph Giffney and welcome to the Community!

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.
