Hello @alan_2809,
For this, I'd suggest using a third party reverse proxy such as Caddy, nginx, Apache, or HAProxy. That will have the added benefit of allowing you to host more than one HTTPS site on the same IP address.
I'll update the documentation to give examples for each of these, but in the meantime, each one of the HTTP servers I suggested above has pretty good documentation for how to set them up as reverse proxies and how to set up TLS certificates.
