Hi
I have entered new ddns.net name to one of the gateways i have installed and while
pressing the save button got "unable to resolve host" error
The name is resolvable ...
Is the Portal lazy ?
Any info is welcome

Looks like ddns.net does not update all it’s authoritative servers at the same time, this
is from the portal server:
[chris@portal ~]# nslookup gilboa-gw.ddns.net
Server: 192.168.1.1
Address: 192.168.1.1#53
