[SOLVED] DynDns error since 17.7

[vince]

Hi, we have a dual stack (IPv4 + IPv6) connection, a modem in bridge mode and pppoe0 on the OPNsense box.
WAN is configured as PPPoE for IPv4 and None for IPv6 since we currently do not make use of IPv6 anyway.
From 17.1 to 17.7 DynDNS was removed from core and is available as a plugin, wich we installed, but it does not work for us anymore.

It seems to have something to do with IPv6 (see the last, topmost, log message from curl for selfhost) but that's as far as I get

I just solved it myself. The WAN interface was not set as the default gateway, instead our coreswitch was selected which uses another wan connection as his default route.
