Daemon.err odhcpd[1953]: Failed to send to ff02::1%lan@lan2 (Address not available)

My log is flooded by these messages.

Found this Odhcpd failed to send to ff02::1 - #2 by mikma , but I don't have odhcpd-ipv6only installed, using odhcpd, so this solution does not work for me.
Is there any way to fix it?..
