This could be the case. This happen when there’s a power drop from the public system, obviously the system is shutted down improperly, after some minutes or more when the power is up again I lost the red0 nic, but only red0. Green0 works as usual.
I have optic fiber service and the ip is served by the ISP’s dhcp server. As mentioned in original post I have to setup red0 again to get internet access.
