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:

The name servers the Portal uses must have queried one of ddns’s name servers that don’t
have the A record yet.

look here ...
Server:
1dot1dot1dot1.cloudflare-dns.com
Address: 1.1.1.1
Non-authoritative answer:

What servers the portal look at ?
Maybe you should point it to more quick update server ?
it is needed specially for dynamic address based gateway to get their new address as
quick as possible in case of address change

Hi Ronen,
What I am saying is that there are 5 authoritative DNS servers for ddns.net
<http://ddns.net/> but they are not all updating together, two of their servers do
not hold the A record for your host, so it is ddns.net <http://ddns.net/> that needs
to sort their servers out and ensure that all their servers update whenever a host is
changed.
It was just “bad luck” that the Portal queried one of the servers that does not have your
hostname.
It was “good luck” that you queried one of the servers that does have your hostname.
Any recursive nameserver will lookup the authoritative name servers for the domain first,
in the case of ddns.net <http://ddns.net/> there are five, it then selects one of
them (could be any one) and asks it for the A record - if by chance it asks one that does
not hold your record it will get a response that the hostname does not exist.
Regards,
Chris

Hi Ronen,
What I am saying is that there are 5 authoritative DNS servers for ddns.net
<http://ddns.net/> but they are not all updating together, two of their servers do
not hold the A record for your host, so it is ddns.net <http://ddns.net/> that needs
to sort their servers out and ensure that all their servers update whenever a host is
changed.
It was just “bad luck” that the Portal queried one of the servers that does not have your
hostname.
It was “good luck” that you queried one of the servers that does have your hostname.
Any recursive nameserver will lookup the authoritative name servers for the domain first,
in the case of ddns.net <http://ddns.net/> there are five, it then selects one of
them (could be any one) and asks it for the A record - if by chance it asks one that does
not hold your record it will get a response that the hostname does not exist.
Regards,
Chris
