Hi everyone. Upon upgrading my Rancher server (from 2.13 to 2.14) I noticed it became unavailable. Rancher logs have this

2026/06/01 16:18:39 [ERROR] Failed to read API for groups map[ext.cattle.io/v1:stale GroupVersion discovery: ext.cattle.io/v1]
2026/06/01 16:19:24 [ERROR] failed to start cluster controllers c-m-pztbbjwl: context canceled
2026/06/01 16:19:29 [ERROR] error syncing 'c-m-pztbbjwl': handler cluster-deploy: cannot connect to the cluster's Kubernetes API, requeuing
2026/06/01 16:20:04 [ERROR] failed to start cluster controllers c-m-pztbbjwl: context canceled

After scaling the pods down then up, the rancher UI reports that the local cluster is Active, but the last two errors just keep showing up every 2 minutes. Any idea what's going on? The apiserver also has this status

Status:

    Message:               endpointslices for service/imperative-api-extension in "cattle-system" have no addresses with port name ""

Although this might be completely unrelated, I don't know.
