DDNS errors in System Log

[jc1685]

After tracking the recent issues with dnsmasq, I noticed that there lots of errors in System Log about DDNS. I use the luci-app-ddns package to update dnsomatic.com so I can filter things I don't want my kids to able to see.

Even though everything is working the way it is supposed to I have to wonder what these errors mean:

Tue Jan 26 16:29:56 2021 user.err ddns-scripts[2588]: dnsomatic: GNU Wget Error: '4'
Tue Jan 26 16:29:56 2021 user.warn ddns-scripts[2588]: dnsomatic: Transfer failed - retry 3/0 in 60 seconds

A new error is recorded every 60 seconds for some reason.

Here's the relative content of /etc/config/ddns:

config service 'dnsomatic'
        option lookup_host 'dnsomatic.com'
        option username '***'
        option password '***'
        option enabled '1'
        option service_name 'dnsomatic.com'
        option domain 'all.dnsomatic.com'
        option interface 'wan'
        option ip_source 'web'
        option ip_url 'http://checkip.amazonws.com/'
        option use_https '1'

Here's the Wiki article that I used to set up DDNS.

Any insight would be appreciated!

wget error 4 is a network failure.

the ip_url that you have in your configuration doesn't resolve to anything... I'm guessing that is the problem.

Thanks for your help psherman! I removed two lines:

ip_url 'http://checkip.amazonws.com/'
ip_source 'web'

In addition earlier in the wiki is mentions installing ca-certificates which I did.

I'm now error free when it comes to DDNS.

Here's my /etc/config/ddns if anyone else would like to see:

config service 'dnsomatic'
        option lookup_host 'dnsomatic.com'
        option username '*****'
        option password '*****'
        option enabled '1'
        option service_name 'dnsomatic.com'
        option domain 'all.dnsomatic.com'
        option use_https '1'
        option cacert '/etc/ssl/certs'
