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.

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 Ronen - 4Z4ZQ

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

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.

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 Ronen - 4Z4ZQ

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.
