With vpn on signing into bt internet is not easy and have to use a round about way of signing in. If I select not to connect via vpn signing in is easy. Using windows 10.

Hello @islandinthesun,

There are a few general causes for connection errors encountered by Bitdefender VPN and I will list the ones that are more suited for this scenario:

• 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.

If you are currently using the default DNS (Domain Name System) from your Internet provider, switch to a third-party DNS server that might be faster and reliable. Resetting the Internet connection might also help.
