Rocky 9.5 host and I get the following running the command? Aside from physical failure which I highly doubt. What should I be looking at. I need a deep dive rather than high level try this command and see. we’ve ran commands and it has to be some sort of config setting somewhere on bootup. Please excuse my ignorance as I am thrown into the fire here with Rancher and K3s.
Thank you in advance.

@polpmpn1 Hi and welcome to the Forum 😄
So is k3s running on the system? Is your KUBECONFIG pointing to the correct file etc?

@polpmpn1 for example;
```bash
kubectl get pods -A
E0128 16:23:20.138058 25397 memcache.go:265] "Unhandled Error" err="couldn't get current server API group list: Get \"https://127.0.0.1:6443/api?timeout=32s\": dial tcp 127.0.0.1:6443: connect: connection refused"

The connection to the server 127.0.0.1:6443 was refused - did you specify the right host or port?

Most likely and if you could describe what you mean? What should I check? Like I said I am thrown into this fire so I assume things have been modified but I dont know what I dont know.

@polpmpn1 check if `/etc/systemd/system/k3s.service` exists, how was k3s installed (check history command).

My background is sysadmin in datacenters from a windows\linux virtualization perspective heavy focus on VMware. There is no VMware here. Just straight hardware with Rocky 9.5. Now if this makes sense, my host is "'salted with configurations why I assume modifications…

@polpmpn1 really need to see how k3s was installed on the system, I see in your output a systemd override. Note I only run openSUSE and SLE…
There should be a `/etc/rancher/k3s/k3s.yaml` with a `server:` entry?

@polpmpn1
This file… k3s.yaml, but also inspect the `/etc/systemd/system/k3s.service` file. You need to look at the contents of both. But seems to me if k3s isn’t running…

@polpmpn1 those two lines
Having non-zero… and in the kernel… are commented out correct with `#`
What are the $MODE $ARGS variables set to?

@polpmpn1 maybe those values are set via the salt config? Or some config file that is sourced (a Rocky linux thing perhaps…).

You are correct. Ok. That answers that. So then im setup fine with my node, this is a salt issue then correct? im geographically disparate from the Salt server and dont know the who what where on that. Is salt part of Rancher, K3s?

@polpmpn1 I’m assuming that $MODE is server, then $ARGS for the cluster, ip address and the plethora of options for k3s that can be configured. I suspect it’s not populating hence the k3s service is not starting?
Salt is a separate tool for configuration, management of a system.
