Sorry to hi-jack this 2 month old thread; but I actually had the same
problem and having it in "DEBUG" log isn't quite enough for me.
Basically there's a feature of my app that could use the failure mode for
diagnostics: "timeout" in our use-case typically means someone forgot to
open their firewall where "connection refused" means we probably have the
wrong connection information. Ideally, this would get surfaced in my GUI,
instead of someone needing to ping/telnet/netcat on the terminal to
disambiguate these cases.
Not absolutely critical, but just thought I'd add some feedback in favor of
adding this to the ConnectionFailed case class.
