Hello All, My cluster details are: • Rancher 2.5.8 • RKE 1.2.13 • Upstream HA cluster Issue: • Suddenly Rancher UI stopped working • UI Error: 503 Service Temporarily Unavailable What can be the issue and how to check it? Please guide. I have also lost my KUBECONFIG file, how can I restore/retrieve it?
Could you please help me solving this issue? @fast-piano-59234 Do you need more details?

There are some troubleshooting steps at, probably start with Could be anything at this point.
rke util
has commands to retrieve state file and kubeconfig.

Thanks a lot, I'll try this.
@fast-piano-59234 Thanks, I did troubleshoot and found that someone had updated the Rancher Deployment YAML and added "hostport: 80" under "ports" section, due to this rancher pods were gone in pending state with event 0/3 nodes are available: 3 node(s) didn't have free ports for the requested pod ports. I just removed "hostport: 80" and Rancher started properly.
