[Koha] Reverse proxy - Intranet

[Victor Barroso Oliveira]

Good Morning,
My Koha is installed on a web server with a reverse proxy server at the
front.
SSL is on the reverse proxy.
The OPAC of my Koha installation is normally accessed via https. However, I
cannot access the intranet (installed on port 8080) with https, only with
http.
In this case, is there any need for configuration in biblio.conf or
ports.conf?
What would this configuration be?
Thanks,
Victor
