Hi, I am trying to add the agents (worker) nodes to the rke2 server, but the "rke2-agent" service is stuck in "activating" state with an error msg "failed to get CA certs: ". I am unable to find any recommendations for the issue. So please help me in fixing this issue.

does connectivity between agent and control-plane work?

From the agent, could you check:

nc -zv $control-plane-ip 9345

where $control-plane-ip is the IP of the control-plane

Yes I see that firewalld is blocking the connection so disabled it on all the nodes. Now the first worker node got added, waiting for the rest of the nodes to be added

nc -zv $control-plane-ip 9345

is connecting from the agent nodes

@bland-account-99790 2 out of 3 worker nodes are added successfully to the master node, the third node is still stuck in activating state with a msg "Waiting to retrieve agent configuration"... any suggestions please

no ipv4 found?

Can you check the interfaces and routing table of that worker node?

Yes we are using IPV6 and will check the interfaces and routing table

ipv6-only is currently not supported in rke2, we are working on that https://github.com/rancher/rke2/issues/2861

were you using ipv4 in the other workers and ipv6 on this one?

No I am using IPV6 on all the workers

There is some confusion with IPV4 and IPV6 configured on the worker nodes....Let me check and get back to you....Thanks 🙂
