after upgrading from Rancher 2.2.8 to 2.3.2 single and K8s from 1.11 to 1.16, we are having the following error:
[ERROR] ClusterController c-hdx96 [user-controllers-controller] failed with : failed to start user controllers for cluster c-dzrz7: failed to contact server: Unauthorized
Which server is denying the request?
We are having also some errors about handshakes on:
- master: “http: TLS handshake error from 127.0.0.1:50508: EOF”
- registering a new cluster controller/rancher-agent: “level=error msg=“Failed to connect to proxy. Response status: 200 - 200 OK. Response body: node.management.cattle.io “c-dzrz7/m-6a7f4a83c4e6” not found” error=“websocket: bad handshake””
Meanwhile, on Rancher UI, we can’t see any information on the dashboard and the nodes page is outdated.
