Cluster failed to to reconcile etc plane

A few days ago I needed to update the ssl certificate used by rancher. After that, the cluster had problems registering master node.

Tried adding new master nodes, restarting, removing and nothing worked

I checked the logs in service-cluster-master-2 and saw that it is not able to connect via websocket to the rancher’s server.

Rancher server 2.2.8

Can anyone help me?
