ddns not updating Cisco C827 w/ 12.4.23

The only error shown in the debug is "DATA START 404" see below.

Everything else is working as desired, all my internet traffic is passing thru this router now.

But, I see when I check my services at that the ip has not been updated.

Someone must have gotten this feature working, Any suggestions?

I have also attached my config (with a passwords and usernames changed:)

Re: ddns not updating Cisco C827 w/ 12.4.23

Don't know if this is the cause but in your config you have the following..

ip ddns update method DynDNS



Between "update" and "system" you have "%3F" where you should have a "?"

To add a ? to a config you need to do CTRL + V first.

As I said, I'm not sure if this is the cause of your issue but worth a try.

Yes, I have since changed that. I was hoping someone would recognize that 404 error. I did see a suggestion that it was too long a password being sent to But, I have also shortened mine to 5 characters.
