[Ddclient-support] Ddclient problem updating IP: "skipping update"

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hello,
i use the dinamic ip service (dyndns) in my server.
I used ddclient to update my remote configuration at dyndns.org....
Until yesterday all work well, but today my ddclient can't update the
ip address of my computer and so my server is no more accessible from
the net.
I don't change the ddclient.conf file.
This is my conf file...i knows that it is correct, but printing debug
infos it show me something not clear and strange:

# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf
daemon=120
syslog=yes
pid=/var/run/ddclient.pid
ssl=yes
protocol=dyndns2
use=web,web=checkip.dyndns.org/,web-skip='IP Address'
protocol=dyndns2
server=members.dyndns.org
login=*****
password='*****'
custom=yes, *****.net

I tried also with this command:

ddclient -daemon=0 -debug -verbose -noquiet 2 /etc/ddclient.conf

and the result is:

Why it tell me "skipping update"? it doesn't show me the problem...

Thanks
