Disabling SSL on Self Hosted Landscape

Running Ubuntu 24.04 Server with self-hosted landscape behind router/firewall. Router/firewall utilizes HAProxy for reverse proxy and SSL validation with a wildcard certificate for my many sub-domains within my private network. How do I configure landscape to work with my wildcard certificate and HAProxy? Is it possible to disable SSL on the landscape server and allow port 80 connects only?

It isn’t possible to disable SSL. There are all sorts of hoops you can jump through to trust the self-signed certificate, but at that point, you may as well get a free SSL certificate from LetsEncrypt using certbot?
