Connect to a WinCC Unified Web Server over the internet using AWS

I have WinCC Unified Runtime Web Server running on Windows 10 Professional x64 (OS Build 19041.450) on the local LAN side of a router connected to the internet. I want to be able to connect to the website over the internet, using DDNS, from my phone or tablet using an HTML5 browser like Chrome.

1) I can browse to the website from any computer or tablet on the local LAN, login with the admin user account and view the live data from an S7-1200 PLC. No problem at all.

2) I have created a DDNS account so that the Router WAN IP Address is always accessible via the same DDNS name and have configured the router to forward ports 443 and 8443 to the WinCC Unified Web Server IP Address on the LAN.

3) I have loaded version 2 update of WinCC Unified and TIA Portal v16 and have selected the WinCC web server IP address with the check box within the "User Administration" section of the WinCC Unified Configuration.

4) I have re-created the self assigned certificate from the beginning using different admin user credentials and have exported the certificate to my android tablet and another laptop with Windows 10 on the internet.

5) From my Android tablet or Windows 10 laptop I can connect to thehttps://DDNSweb address and am forwarded to the Win CC Web Server and the home page is displayed.

6) When I click on the "WinCC Unified RT - Start Your Project" button the error message is "SwacLogin: Error during componet/s creation"

What could the problem be and how do I resolve it? I have tried clicking the "User Management - Manage Your Users" button first but it shows the message "Redirect to login page..." and does not open the login window.
