My DDNS somehow broke?

I had DDNS working for a while, but checking my logs today I see it's
broken.
Feb 1 14:07:17 blue dhcpd: Unable to add forward map from
65-182-251-202.hsi.web-ster.com to 65.182.251.202: timed out
Feb 1 14:07:17 blue dhcpd: Unable to add forward map from
216-105-64-101.hsi.web-ster.com to 216.105.64.101: timed out
---------------------------------------------------------------------
Here are the appropriate lines from the dhcpd.conf
# Dynamic DNS stuff
ddns-update-style interim;
ddns-updates on;
ddns-domainname "hsi.web-ster.com";
ddns-hostname = binary-to-ascii(10, 8, "-", leased-address);
key ddns {
algorithm HMAC-MD5;
secret "my_base64_sekrit_key";
};
zone hsi.web-ster.com. { key ddns; }
zone 255.182.65.in-addr.arpa. { key ddns; }
zone 254.182.65.in-addr.arpa. { key ddns; }
zone 253.182.65.in-addr.arpa. { key ddns; }
zone 252.182.65.in-addr.arpa. { key ddns; }
zone 251.182.65.in-addr.arpa. { key ddns; }
---------------------------------------------------------------------
Here's the appropriate lines for each zone file
zone "255.182.65.in-addr.arpa" {
type master;
allow-query { any; };
allow-update { key ddns; };
notify no;
file "255.182.65.in-addr.arpa.dns";
};
key ddns {
algorithm HMAC-MD5;
secret "my_base64_sekrit_key";
};
---------------------------------------------------------------------
My named is accepting DDNS updates. If I update it manually as follows
it works fine:
server ns1.web-ster.com
key ddns my_base64_sekrit_key
zone hsi.web-ster.com
update add 216-105-70-22.hsi.web-ster.com 600 IN A 216.105.70.22
send
It just seems to be DHCPD -> Named updates that are broken. Checking the
named logs I'm not seeing anything. I am seeing the packets hit the
server with TCPDUMP, it's just not updating DDNS. I'm not sure where
else to look. Any ideas?
