I was trying to do the t.swift tutorial again and I keep getting stuck on this error. What does it mean to not be able to find a valid host? How do I remedy this? And another question on the side what's the difference between <a href="mailto:swift-user@ci.uchicago.edu" target="_blank">swift-user@ci.uchicago.edu</a> and <a href="mailto:swift-user-owner@ci.uchicago.edu" target="_blank">swift-user-owner@ci.uchicago.edu</a>. For help we can send to both? or usually just swift-user?<br>
