How do you switch to Let's Encrypt's staging servers?

So if the Caddyfile is correct, there seems to be some kind of disconnect between Caddy and the service.

I find myself wondering if the service is configured with a -conf flag and you don’t supply the same flag when you run it from the command line?

@Howdy

I assume that Caddy should only display just “http://:2015” if the Caddyfile is empty/wrong?

If you don’t configure it with a Caddyfile, yes, it will output this - Caddy is programmed to serve this interface by default, for convenience of local development (just cd to the web root, run caddy, browse to localhost:2015)

@Howdy

I can only find one Caddyfile on the server, and running “caddy -validate” says it’s valid, yet I only see “http://:2015”.

The only reason I can think that this would happen is that you’re not running Caddy in the same PWD as a file named Caddyfile or you haven’t supplied the correct -conf flag.

@Howdy

systemctl seems to access environmental variables, while “caddy” doesn’t.

How are those variables set, exactly?
