Custom Git clone url - Admin area - Where do i put the ssl certs for it?

Im trying to change the Custom git clone url to an other url (other domain) that is https but im unsure where should i put the ssl certs for the domain…
Im using non-boundled nginx wbeserver.

Any idea?

I’m interested in that too since we’re using a specific port for gitlab.

Im trying to setup an reverse proxy for it an use the proxy to provide the cert… But so far unsuccesful
