Caddy and macOS Tailscale from App Store

I’m trying to get Tailscale and Caddy working together on macOS and I’m running into problems I guess might be related to the App Store install.

When curl’ing my hostname I get:

curl: (35) error:14094438:SSL routines:ssl3_read_bytes:tlsv1 alert internal error

Tailscale version

1.26.2

Caddy version

2.5.1

Caddyfile

{
	debug
	log {
		output file log/caddy.log {
			roll_keep 1
		}
	}
}

my-host-name.turkey-snapper.ts.net {
	reverse_proxy /* localhost:9000
	tls {
		get_certificate tailscale
	}
}

Caddy logs

From running caddy with sudo:

What stands out here is:

dial unix /var/run/tailscaled.socket: connect: no such file or directory

I’m guessing this might have to do with the app store vs standalone vs tailscaled differences. I haven’t tried any other form of running it.

I haven’t found the socket file at all on my system, no idea where it lives.
