hello, i have fleet running under https://fleet.example.com:23788 and I have created a self-signed cert for it. I am getting certificate verify failed in Osquery. What should be the CN in the cert? I have tried fleet.example.23788, https://fleet.example.23788 and they both failed.

The CN (common name) should be set to the FQDN of the server which in your case should be

fleet.example

.

Thanks!
