Hello. This appears to be a request for general technical support rather than a bug report. Let's move this to a discussion instead of an issue.

[jchambers]

This appears to be a network or configuration issue of some kind, and does not appear to be a bug with Pushy. I think you're going to need to share some more information if you want help debugging the issue. In particular:

1. What version of Pushy are you using?
2. What operating system are you using?
3. What version of Java are you using?
4. Can you describe your network configuration? Are you behind a firewall? Are you using a proxy?
