Test connectivity with ICMP ping messages.This runs over WireGuard; tell us which WireGuard tunnel to use by
running from within an app directory (with a ‘fly.toml’), passing the
‘-a’ flag with an app name, or the ‘-o’ flag with an org name.With no arguments, test connectivity to your gateway, the first hop
in our network, to see if your WireGuard connection is working.The target argument can be either a “.internal” DNS name in our network
(the name of your application) or “gateway”.
