Hi guys!
I have a question regarding the web server that Proxmox serves on 8006.

Is there any way to control it without putting a reverse proxy in front of it? We need to disable the possibility of downgrading to HTTP/1.0 protocol for it because it's considered a vulnerability by the auditor team ( yes it has TLS and it's protected by firewall rules, but they still insist).

Is there a way to set it up or "patch" this "vulnerability"?
