1841 router + ip ddns not available status

I have an 1841 router with software version 12.4.(19a). each time I try to configure DDNS on the router i get the message

option 1 under the fa0/0 WAN interface

testbed01#sh ip ddns up

Dynamic DNS Update on FastEthernet0/0:

  Update Method Name            Update Destination

  no-ip.org                                  not available

option 2: under the dialer 0 interface

Dynamic DNS Update on Dialer0:

  Update Method Name            Update Destination

  hostanme                      host: vpn-dimitrib.no-ip.org

  no-ip.org                          not available

both times I see the service as 'not available' and when I run the 'debug ip ddns update' I see no output from the debug nor do I see anything in the show logs. Why would this not even produce an output? or work for that? did I miss something in the configuration or is there something on the ISP side that I've missed.

configuration from the router:

testbed01#sh run | b ip ddns

ip ddns update method no-ip.com

HTTP

  add http://EXLUDUED@EXCLUDED:EXLUDED@vpn-dimitrib.no-ip.org/nic/update?hostname=EXLUDED@vpn-dimitrib.no-ip.org/nic/update?hostname=<h>&myip=<a>
