Re: DDNS issue, DDNS not updating - Page 2

Steve Harvey · ‎02-22-2016

I have configured Dyn DNS on my Cisco 1921 router (15.3(3)M3) but it is not updating the host-name. I used debug command too to see the DDNS updates but no update or information shown in response to debug ip ddns update command. Can anyone please suggest what is missing in following configuration?

I faced the same issue most of the time. Becuase I missed "?" in the configuration. And Afer update restarts the router (Out of office hrs).

If not, please provide debug logs.

I will try to restart it tomorrow.
there are no any debug logs... or, I don't know how to enable it for DDNS
