minikube and how to debug api server error

Question

I dont get what is going on with minikube. Below are the steps I undertook to fix the problem with a stopped apiserver.
1) I dont know why the api server stopped. How do I debug? this folder is empty:

 --> EMPTY ~/.minikube/logs/

2) After stop I start again and minikube says all is well. I do a status check and I get apiserver: Error. So...no logs..how do I debug?

3) And finally what would cause and apiserver error?

Thanks

~$ minikube status

kubelet: Running

Can you please share the logs? minikube logs – Rowney

you can also start the minikube with minikube start -v=7 and post the results or check if there is something that could help recognize the issue. – Telegraphese

please run "minikube start" command with the extra parameters to log --alsologtostderr -v=3 for additional logging. See if that gives any additional information. And also see if the below reference help you to restart the minikube apiserver manually. #50016581 – Tobytobye

@Altimetry Have you tried any of the above suggestions? – Neighboring

I'm having the same problem. This is on minikube version 1.33.1 running on Docker on MacOSX 14.6.1

$ minikube status
minikube
type: Control Plane
host: Running
kubelet: Running
apiserver: Stopped
kubeconfig: Configured

This problem seems to come up intermittently, usually not after a minikub delete and minikube start, but more consistently if I run minikube stop and then minikube start.
