Very simple cluster: rancher server 2.3.0-alpha5 in docker container, Amazon EC2 cluster with AWS provider, 1 master, 1 worker on EC2 nodes. Nodes were disconnected from the Rancher Server for a while and once the connectivity was fixed, the cluster was still not available and ive seen "tls: bad certificate" error in the logs of the rancher server. I've tried many different things, nothing helped. I am just very concerned what would I do if it happens on production cluster, so I am searching for the way to fix things. Now my master is dead completely, as I've tried to remove it and add new master This is how it looks like
