Summary:
When Xcode can't reach a server, it simply fails with an error "a server with the specified hostname could not be found". 

The error message is very generic, and doesn't help you understand what's going on. There's no mention that this is related to a server configured in Xcode.

Steps to Reproduce:
1. configure Xcode to access a server on your intranet
2. go out of the intranet, where you can't reach the server from
3. close and reopen Xcode, you get the error mentioned in the description.

Expected Results:
Either we should not get an error, as there's nothing Xcode should be doing with the server during startup, or the error message should explain what the issue is.

Actual Results:
Bad error message displayed.

Version:
XCode 6.3.1 6D1002

Notes:
This is frustrating and happens a lot for users who have internal build machines, but frequently open Xcode from outside of the network.

Configuration:
Vanilla Xcode, with Xcode server running on a different machine in an intranet/VPN. 
When Xcode is executed from a different network, generic error message is displayed.
