    Enter the exact same update URL in a browser and see what is really returned.

    I  forgot to add that to original post, when I put that URL in a browser it returns "good xx.xx.xx.xx" and the update shows in my dnsomatic history as a successful update.

    Then the problem is with your Cisco 871, and you'll want to refer to Cisco support.  Most likely nobody can help you here, because the issue is not related to DNS-O-Matic, but to this update client.
