the DNSExit.com present for updating DDNS no longer functions as of sometime after November 20th 2023.

The current error output is
Code:

In-a-dyn version 2.12.0 -- Dynamic DNS update client.
Failed connecting to ip3.dnsexit.com: Host is unreachable
Communication with checkip server ip3.dnsexit.com failed, run again with 'inadyn -l debug' if problem persists
Retrying with built-in 'default', http://ifconfig.me/ip ...
Please note, https://ip3.dnsexit.com/ seems unstable, consider overriding it inyour configuration with 'checkip-server = default'

https://github.com/mirror/dd-wrt/blob/master/src/router/inadynv2/plugins/dnsexit.c#L45

Checking DNSExit.com documentation the current api use is as follows:
Code:

curl https://api.dnsexit.com/dns/ud/?apikey=myapikey -d host=mydomainaddress


Additionally, before this DNSExit.com preset stopped working, the enable IPV6 function did not work correctly. Two requests were made to DNSExit.com, the first being the IPV4 address and then the IPV6 address afterwards which would overwrite the previously set IPV4 address.

Yes, it says that external IP-check is unstable.

http://ip3.dnsexit.com/

Code:
ip3.dnsexit.com: Host is unreachable


there is nothing more in the log except that you should try another IP check server

This is hardcoded in dd-wrt source code as I have edited in the original post.

https://svn.dd-wrt.com/ticket/7616

The solution is hidden somewhere in the ticket. Smile

But how are we supposed to fix it?
The IP check server works for me.

I could only imagine a switch "use default server"
Or a field "custom server"

But you have to convince the dd-wrt developer of this first.

Edit: the ticket will not help much, because it has nothing to do with the api and the IP check server can be configured

By the way, your IP Check error is an SSL error.

The IP Check server does not support SSL

So, uncheck "use SSL" and test and report back Cool
