It was indeed by proxy server at work, when I got home and tried it over my broadband connection it worked fine.
I however am having another problem, the cookies don't appear to be working in Isilo. It sync'ing my main zipcode, but not the optional location. It works fine when I open my browser and go to the link directly, I look at the cookie being stored on my laptop and it does have my local zip and the optional one. I copied the info in the cookie on my pc into the cookies section within Isilo for that link, but it is still not working. Any ideas.
