The traefik load balancer keeps on crashing. Is this known behavior for fedora 36? In a previous cluster this ended with a message:

Perhaps iptables or your kernel needs to be upgraded.
had to change the firewalld backend from nftables to iptables in
/etc/firewalld/firewalld.conf
that fixed it, after a
sudo systemctl firewalld restart
and a restart of the cluster
