HA public access with own cert and own pubic subnet

Configuration
1

I am pretty sure I am missing something very simple. I have my own subnet and my own wild card certificate. I am looking everywhere on how to add my own information. If anyone can point me in the direction on adding the SSL cert and using my own subnet - Not using let’s encrypt and duck dns I would be very grateful. Again I am certain I am missing something… The google machine is simply not being very kind.

Thank you in advance.

I use nginx reverse proxy

SSL cert for domain is setup in Nginx where https requests are received and forwarded http to HA server locally(there in separate Docker containers on same host)

EDIT
Also check link below and you can just add cert to HA and send requests direct to HA

It’s comfigured in http section
