Hi, Currently am found out that my DDNS test is error on my flint.
I’m curious to know what is the problem, pls?
Thanks!
The error says much. Your system has a listed DNS server. And this server is not able to find the DNS name.
Just open a CMD in your computer and try to ping the dyndns address.
If this works, try nsloookup [dyndns domain] (without []) … Than use nslooup /help to get the syntax for specify a DNS server. nslookup [dyndns domain 8.8.8.8] or nslookup @8.8.8.8 [dyndns domain] can ask the the Google DNS servers.
If the Google servers doesn’t know the domain, there is a error in registration. If there is a finding, but the wrong IP, it could be an issue with the renewal…
Alright 
noted with thanks
