it seems the default is force https but I do not know why dyndns doesn’t offer anymore a free ssl service
I understand why I get rid of them many years ago
╭─stephdl@leo.lan ~ ‹master›
╰─➤ curl -k https://checkip.dynu.com
Current IP Address: 90.76.3.30%
it seems that dynu could provide a free service but I think we need to trick it
changeip too
╭─stephdl@leo.lan ~ ‹master›
╰─➤ curl -k https://ip.changeip.com
90.76.3.30
could you try it ? over ssl and not encrypted, I use it locally since along time on my server
Ok stephdl, I modified as you wrote to me, on 2 servers that use the same service. I’ll update you as soon as possible. At the moment, thank you as always.

check the external IP and reboot the box, if it has changed then check your dynamic dns provider to validate the change. Thank you too @france you found a valid bug
Ok, let’s say that thanks to you who solve it … I just reported it.
However, I restarted the router and the clients work, currently in http and not https. But one of them gave me a mistake, I don’t think anything about that. Anyway I’ll go around.
protocol is undefined like you see the above message
I fixed the issue in the 2.0.4 about no ssl and dyndns, see:

Hi, I updated the two servers with the ddns, but on one of the two it reports me by email error:
Nov 27 22:31:57 golub ddclient[4246]: WARNING: file /var/cache/ddclient/ddclient.cache, line 3: Invalid Value for keyword ‘ip’ = ‘’
Did you modify your settings or you just updated your server ?
What is the content of the file ?
I started the update, but this error reported it before … the first server does not give errors, the second continues to report the previous error.
WARNING: file /var/cache/ddclient/ddclient.cache, line 3: Invalid Value for keyword ‘ip’ = ‘’
WARNING: found neither ipv4 nor ipv6 address
Hi all,
I am following this thread because my dyndns does’t work properly. I have to update manually every 30 days at noip.com.
If I try to change the frequency in the Manager (980) I received:
Tasks completed with errors
# (exit state)
If I reload the page, the new frequency is there.
I receive this error using checkip.dyndns.org or checkip.dyndns.org:8245 or ip.changeip.com with SSL or not.
Then if I run:
# /usr/sbin/ddclient
User root receives this email.
WARNING: found neither ipv4 nor ipv6 address regards, [ddclient@titi.toto.org](mailto:ddclient@titi.toto.org) (version 3.9.1)
But if again I run /usr/sbin/ddclient, then user root receives no more warning message.
# curl -k https://checkip.dynu.com
Current IP Address: 11.22.33.44
# curl -k https://ip.changeip.com
11.22.33.44
<!--IPADDR=11.22.33.44
But, since this is my main NS server, I don’t like to test too many things on it.
I don’t mind to update manually every 30 days.
Long time ago, I tested the noip.com client on a LOCAL VM and it worked correctly…

EDIT:
Also, another email to root:

Hi Stephane, this morning I received other email messages after the upgrade, I am sending them to you to update you of the change made

what about of

the problem is on your side I bet, you have to dive to understand
