I turned everything off and now it is suddenly working. Thanks for your help.
Done all of that. Even rebooted. Still doesn’t connect.
I added this files to both Norton and Malwarebytes but still no joy. Do I need to reboot after adding these? I even turned both of them off and still not connecting.
Many thanks for your very quick reply. No VPN enabled. My profile is set to PRIVATE. File requested attached.
