Unable to connect to via `ysqlsh`
After following the instructions here, I have what appears to be a functioning Yugabyte cluster, but I'm not able to connect using the command kubectl exec --namespace yb-demo -it yb-tserver-0 -- /home/yugabyte/bin/ysqlsh -h yb-tserver-0.yb-tservers.yb-demo.
If I try it, I get this error:
Here are the running pods:
Here's the output of kubectl describe pod yb-tserver-0 -n yb-demo:

FYI, I installed the cluster using k0s with defaults, except I'm using Calico for networking.
