Cannot authenticate FOG in host to proceed deploy

[***Redbob]

I’m trying to deploy an image to a PFsense Appliance (APPLIANCE FIREWALL 4 LAN I226-V PROC J6412 8GB DDR4 E 256 SSD NVME HDMI/DP) and I cannot authenticate. PXE could get IP by DHCP in each of 4 NICs present in the appliance (obviously I plug network cable in just one of them), but after the actions menu and before images menu, when FOG asks for autentication, we fill auth fields but nothing happens, and FOG cannot overcome the screen I attached here below.

Any ideas?
