Same problem here,
it seems to be something with kubernetes, I don’t understand well, but I think it only points to the host’s default IP and not to all IPs that are on the truenas host.
I really appreciate if anyone knows how to solve it.
I’ve already thought of some iptables rule to make all connections to the zerotier IP forward to the physical IP of the host, but I think there should be a “more appropriate” solution, besides I don’t know well about iptables to create this rule
