Hi everyone, I have an issue when running `sudo fleetctl preview` ?
System: MacOS Monterey.      CPU: Intel
Error: Failed to install: download archive <https://github.com/fleetdm/fleet/releases/download/fleet-v4.12.1/fleetctl_v4.12.1_macos.tar.gz>: self signed certificate in certificate chain

Sorry to hear you're running in to trouble! I did a quick test and it looks like `fleetctl preview` isn't having any odd issues. I'm doing a bit of research to see what might be interfering for you.

It looks like this may be related to a network proxy. If that rings true, check out <https://medium.com/@ogbemudiatimothy/using-npm-install-behind-a-corporate-proxy-server-db150c128899|this article> and hopefully you'll be well on your way.

If that doesn't do the trick for you, please  send over a screenshot of everything you see after running the command (feel free to redact any sensitive information) so we can get a better feel for what is and isn't working and where things are breaking down. . I'd also like to see what versions of node, npm, Docker and `fleetctl` you're running:

```node -v
npm -v
docker -v
fleetctl -v```


Thanks, it was my VPN cause the issue. :sweat_smile:

They definitely like to muddy up the works.
