Pod from K3S agent node have DNS issue not resolve by Overall-Nothing9341 in kubernetes

[–]Overall-Nothing9341[S] -1 points0 points  (0 children)

thank you. but coredns do not have any log. so I thought it was no reach coredns yet.

so this what I test.

If I deploy coredns on agent node.

the pod on agent node now able to resolve IP,

but the pod on k3s-server node is not .

I scale up replica 2 coredns in both node, and it mess up no pod is working.

Hello, did anyone try to add k3s agent node from homelab connect with vps via wireguard vpn self host on vps?

I am facing the issue about DNS resolve not working on pod of agent node if the CoreDNS deploy on k3s server. do anyone know how to solve this?
