Review Comment:
Ok I figured out what's going on. It's not actually a TLS error, is an error
with `location` itself.
When `0.0.0.0` is supplied, this means the server is listening on it, but
also with these changes it serves as the location that is returned as the
endpoints for any FlightInfo returned by the server. And trying to connect to
0.0.0.0 isn't going to work. Hence why substituting 127.0.0.1 works, as that
can be connected to.
