VPN error 720 on Windows A connection to the remote computer could not be established. You might need to change the network settings for this connection.
Yesterday your vpn connection was working just fine however today when you try to connect to the same connection you get an error error 720 a connection to the remote computer could not be established you might need to change the network settings for this connection of course you don’t need to change any network settings as long as they are correct and probably no settings have changed since yesterday so as usual windows gives you a very misleading error message what might have changed is windows itself most probably some windows update came overnight and that is what ruined your vpn connection but instead of searching which update that was and disabling and uninstalling that the solution to this problem is much simpler and it will be the same for most windows versions that is windows 7 windows 8 windows 10 and windows 11. all you have to do is go to device manager open the network adapters drop down list delete each and every of the WAN miniport adapters you can do that by right clicking each and every one of them and pressing uninstall on each of the WAN miniport adapters after you do that right click on the network adapters and choose scan for hardware changes option that will reinstall all the WAN mini port adapters and your vpn connection will now work
