04/09/2025, 12:28 AMI have been battling with Cilium & getting a RKE2 cluster provisioned with Rancher Cluster Manager Against my Harvester Cluster. All VM's will create and be running but the initial Node in the Cluster will sit at "Waiting for cluster agent to connect".
I have followed instruction on MTU 1450 for VLAN support and setting bpf.vlanBypass : [0]
Any other settings or cloud init requirements other then iptables that I am missing?

Copy code
k -n cattle-system get po -lapp=cattle-cluster-agentmillions-microphone-3535
04/09/2025, 8:20 PMmy guess is an issue with the self-signed tls ca cert

04/09/2025, 8:24 PMThx @millions-microphone-3535 for the response. When ever I build a cluster using flannal or calico I don't have an issue. It's just cilium

04/09/2025, 8:26 PMmaybe a cilium configuration issue? see what the cluster agent logs say

04/09/2025, 8:26 PMthen might wanna look into cilium logs - sorry, not too familiar with it

04/09/2025, 8:29 PMfwiw, it's wss connections between your guest cluster and rancher; not sure if cilium works with that OOB
