Yesterday I Installed and configure Fail2Ban on my proxmox.
I checked that Fail2Ban is running and active.

But when I try to login my proxmox from web GUI with wrong password more than 10 time it's not block my IP.
i don't know where is the problem. someone please suggest me to solve it. I'm restered several time.
