Access WinCC Unified Runtime from the internet

Hello!

I have WinCC Unified Runtime running on Windows 10 Professional on the local LAN side of a router connected to the internet. I am using TIA V18 and WinCC Unified Runtime V18 and local user management. I want to be able to connect to the WinCC Unified Runtime over the internet, using DDNS. 

I created a new certificate authority on the WinCC Unified PC and I have a secure connection when accessing the WinCC Runtime from URL: "https://mypcname/WebRH". 

• I followed this example: https://support.industry.siemens.com/cs/ma/en/view/109804116
• I configured a reverse proxy and changed the files as suggested in the example, now when I try to access the WinCC Runtime from URL: "https://myProxy.com/WebRH i get the error: "The url https://myProxy.com/umc-sso//swaclogin is unavailable."
• I also found this discussion: https://support.industry.siemens.com/forum/si/en/posts/connect-to-a-wincc-unified-web-server-over-the-internet-using-ddns/245172?page=0&pageSize=300#!#pagetop
• I forwarded ports 8443 and 443 and I tried with a reverse proxy.
• In WinCC Unified Configuration I tried with textual name of my Unified PC, I tried with local IP of my Unified PC and I tried with my public IP for my Unified PC but nothing works. I always get the same error.

Did anyone encounter similar problem or found a solution? I would really appreciate any help.

Thank you!

I'm having the exact same issue, has anybody found a sloution?
