Network configuration is missing.

Hi @all -
maybe you can give me a hint.
As soon as I add an ipv6 address to my grommunio system ( Distribution: grommunio Version: 2025.1.1- Opensuse 15.6 just installed)
I receive the message " Network configuration is missing." - or in german "Netzwerkgerätekonfiguration fehlt."

IPv4 and IPV6 is working fine.
Services are available and routing also works fine.

I even switched my ipv4 config from dhcp to manual config, added my gateway, my hostname and the dns servers.
still the same error.
DNS resolution also works fine, the server can resolve itself with its ipv4 and ipv6 address.

what kind of check is happening and how can i fix it?

thx & br

# Before you change this file manually, consider to define the

# /etc/sysconfig/network/config file:
#     NETCONFIG_DNS_STATIC_SEARCHLIST
#     NETCONFIG_DNS_STATIC_SERVERS
