Rancher was working normally, so I added a new node and delete another, after this got error red error.
cannot proceed with upgrade of controlplane since 1 host(s) cannot be reached prior to upgrade.
Inside Provisioning Log this is the error.
[ERROR] Failed to set up SSH tunneling for host [x.x.x.x]: Can’t retrieve Docker Info: error during connect: Get “http://%2Fvar%2Frun%2Fdocker.sock/v1.24/info”: can not build dialer to [c-s5krx:m-42d66165b347]
Inside Conditions tab
Ready False 9 hours ago [Disconnected] Cluster agent is not connected
I used the Registration Command to add new nodes, but now I am not able to add more nodes with this error.
