How to enable port 49285 using virtual host and point to qms page? SMG (Version: 2021.12.3)

I have an SMG (Version: 2021.12.3), scheduled digest email that included a message release button. But the link is https://ServerAddress:49285. The port number is not listening. I follow the step to create a virtual host for port 49285.

But not work. The link I found is not the same GWAVA version. May I have the correct step to enable the virtual host for SMG 2021.12.3?
