Autodiscovery from clients can't discover smb share

[Forssux]

Hi there,

I have installed samba on the Proxmox host and made some shares.

I can access them fine.
nbscan or nbstat on windows find the Proxmox server. Firewall for testing is of on pve and the Datacenter.
Unfortunately the graphical tools in kde/gnome or windows 10 don't list Proxmox. They find other PC's


What am I forgetting?
Kind regargds
