Actually I running a Rancher single node instance installed from Rancher UI. After 1 year, Rancher UI is unusable and I've these logs:

After investigation, I found another cert error on container k8s_agent_cattle-node-agent-XXXX_cattle-system_XXXX:

After 1 year Rancher UI cert is expired, How can I renew it ? I'm running Rancher UI 2.2.1.

Thanks a lot.

Best Regard.
