Deadline Forwarder UBL Problem (V-ray)

Good, we are using third party UBL, we do not have aws portal, likewise I have opened 30304,303067(TCP-UDP) Inbound and Outbound in the windows firewall both where licence forwarder is hosted and in the processing node, but I have no result.

I have tested these hours a trial license of Vray and it has worked perfectly, so the problem must be of the license forwarder.
