The problem was the use of PPTP networking - https://community.spiceworks.com/topic/2269902-pptp-vpn-setup-on-rras-server-not-working sorted me right out!
VPN over LAN fine ... VPN from external client - hell

Forgive me - I am hopelessly out of my depth but learning fast! My first ever server setup!
I have a Windows Server Essentials 2019 instance running and am able to connect via VPN over LAN no problems.
But when I attempt to PPTP VPN from the Internet my client fails to connect.
Nothing is seen in the Event Viewer (unlike when on LAN) I have installed wire shark and I can see the connection is successfully made....
So I am relatively confident that I am getting past the router - i.e. port 1723 is open and connecting to the server?
Could anyone recommend anything to get this working?
Thanks in advance for help and apologies for my ignorance - will definitely be a PICNIC problem!
Thanks,
Paul

2021-01-10T00:17:44.573+00:00 At the client side I get 'The VPN connection between your computer and the VPN server could not be completed. The most common cause for this failure is that at least one internet device (for example a firewall or router) between your computer and VPN server is not configured to allow Generic Routing Encapsulation (GRE) protocol packets.
I have tried turning off all firewalls in the chain to no avail / difference in outcome.
