>> Hello Daniel, I think we should avoid `localhost` usage here and instead use `URIBuilder` test library util and then pass it  `InetAddress.getLoopbackAddress()` as the host. That should help avoid issues related to `localhost` being mapped to some other address and at the same time allow constructing the right URL when `InetAddress.getLoopbackAddress()` returns an IPv6 address.

Good catch! Switched to `serverAuthority()`.
