443 port opened on the hypervisor???

[openaspace]

Hello.
Today after a routine port scan to control the hypervisor host ports,
I have found this strange SSL 443 error , where this port...obviously would be closed.

I have controlled the firewall rules at cluster level and host level and only my office static ip's are allowed in the "security group" to connect on management ports like 8006 and 22. Default drop IN setup...(obviously)

Finally I have declared to deny connections on 443 ports, and after a new port scan it now is closed.

Why this happened?!!!!

proxmox don't have any service listening on 443.

do you have tried to look with "netstat -anp |grep 443" to see if something is running on this port ?
