sd+ stopped discovering (unknown workstation)

sd+ stopped discovering (unknown workstation)

running 7.0.0 Build 7013
not sure when this happened but now whenever we attempt to scan we get an error "Unknown workstation" and fills in the workstation info with blank info
so I have to delete the workstation, turn off the firewall on the workstation and scan again and then turn back on the firewall.

Please, this was all working fine before with a global policy for firewall in place.

this is getting so old
