PROBLEM, SFOS 15.01.0 MR-3, DYNAMIC DNS UPDATE - DYNDNS

There is a problem with XG Firewall and Dynamic DNS Update using DynDns as a provider. The system initially updates the IP address to the dyndns hostname but eventually when the IP Address changes although default check period is 20 minutes, the system does NOT update the IP address to the dyndns hostname.

The problem continues whether you check "Use Port IP" or "NATed Public IP". There is nothing on ddc.log it is filled up with that line:

I have also changed the option from "NATed Public IP" to "Use Port IP" and the agent updated the IP to DynDNS but when the IP will change the same thing will happen. ( I am hiding my IP and my host here with xx)
