Steps to reproduce

1. crc stop
2. crc delete
3. crc setup
4. crc start
6. failure:

> oc get nodes
E1114 11:58:42.029032   67782 memcache.go:265] couldn't get current server API group list: Get "https://api.crc.testing:6443/api?timeout=32s": net/http: TLS handshake timeout

Expected

Having crc using microshift and/or openshift to continue to run until shutdown.

Actual

For the last month or two updating crc using OpenShift or Microshift on two different macos laptops with significant memory/cpu capacity I have not seen crc run with stability. After the machine starts, it works for a few minutes or hours, then becomes unresponsive. Sometimes it fails to start from the beginning. When it starts to fail I am unable to connect to the API server, and unable to ssh into the machine:

➜  oc get nodes

Logs

Before gather the logs try following if that fix your issue

$ crc delete -f
$ crc cleanup
$ crc setup
$ crc start --log-level debug

Please consider posting the output of crc start --log-level debug on http://gist.github.com/ and post the link in the issue.

This behavior happens on two different macos laptops with significant memory and CPU capacity. I have been able to deploy some basic containers and have it work for short amounts of time, as well as install operators.

The failure state and behavior are slightly different at times. For example, sometimes trying to ssh into the CRC machine never connects, and other times it immediately reports "read: Connection reset by peer; Connection reset by 127.0.0.1 port 2222"

@shuawest do you have podman desktop or docker running on same laptop?
