DDNS - IP retrieval via web not working

Installing and Using OpenWrt Network and Wireless Configuration
1

First and most importantly: Happy New Year !

I installed the DDNS-scripts on 18.06.
OpenWrt-Router is a DHCP client of a cable modem.

IP detection via Web is not working.

/etc/config/ddns:

config ddns 'global'
	option ddns_dateformat '%F %R'
	option ddns_loglines '250'
	option upd_privateip '0'

config service 'goip'
	option service_name 'goip.de'
	option username 'XXXXXXXXXXX'
	option password 'XXXXXXXXXXX'
	option lookup_host 'xxxxx.goip.de'
	option enabled '1'
	option ip_source 'web'
	option use_syslog '1'
	option domain 'xxxxx.goip.de'
	option interface 'lan'
	option ip_network 'lan'
	option check_interval '1'
	option check_unit 'hours'
	option ip_url 'http://checkip.amazonaws.com'


DDNS-LOG:

I think I can rule out a problem with goip.
Their update URL is working great through the browser.
I also tried alternative URLs for detecting the IP.

Big thank you to anyone willing to help.

You should be using your WAN interface for the DDNS, not your LAN.

Hi !
If I choose "Uplink", which is the DHCP-client of the cable modem, it displays its local ip.
I don´t want it to check on any local ips, but simply retrieve its external IP via URL and
broadcast it to the DDNS-provider.
