There was an error trying to determine the public IP for interface - wan (mvneta0 ). DDNS not working..

[cs08]

Yesterday it worked, today it doesnt.

I use subdomains from(which worked yesterday):
No-Ip
All-Inkl.com (freeddns.org)
freeDNS
for my DDNS.

From the logs it seems that the updatedns() cant figure out my public IP.
I can reach the ipservices myself: http://checkip.dyndns.org

Sep 12 13:57:29 php-fpm 23807 /services_dyndns_edit.php: Dynamic DNS (XXXXX.ddns.net) There was an error trying to determine the public IP for interface - wan (mvneta0 ).

I have also tried:
http://ip1.dynupdate.no-ip.com

Here are some outputs from curling IP Services

Any Ideas?

I've solved it with a script and a cron-job in the mean time:

#!/bin/sh

Fetch public IP with debugging

PUBLIC_IP=$(curl -4 ipinfo.io/ip 2>/dev/null)
if [ -z "$PUBLIC_IP" ]; then
logger -t ddns "Failed to get public IP from ipinfo.io"
exit 1
fi
logger -t ddns "Public IP: $PUBLIC_IP"

No-IP update

NOIP_USER="USERNAME"
NOIP_PASS="PASSWORD"
NOIP_HOST="SUBDOMAIN.ddns.net"
NOIP_RESPONSE=$(curl -s "http://$NOIP_USER:$NOIP_PASS@dynupdate.no-ip.com/nic/update?hostname=$NOIP_HOST&myip=$PUBLIC_IP")
logger -t ddns "No-IP ($NOIP_HOST): $NOIP_RESPONSE"

But I still want to figure out the official fix of course!
