Desktop dies on 1st sync- Mac and Windows

[dillera]

I've tried the Desktop on both Mac and windows, each time I set it up to my server and connect it dies. Here is the log from Desktop:

How do I enable the proxy service that it seems to want?

The word "proxying" here doesn't actually mean it requires a physical proxy of some sort. This error indicates zdesktop is having trouble reaching the server at http://zmail.dillernet.com. At the time when this message was reported were you able to reach http://zmail.dillernet.com directly from browser using the same PC/Mac?
