"This connection was reset" is often actually a browser cache issue. Try clearing your web browser cache and cookies. You can usually get to these settings in most web browsers by pressing CTRL-SHIFT-DELETE while in the web browser.
If you are using a proxy, you may need to clear its cache as well or disable it in your Internet settings.
If you are on a Windows computer, try the following commands:
netsh winsock reset catalog
The only other thing that I can think of might be your firewall (corporate or local) which might be blocking the connection. If course it could always be a virus on either your computer or the web server. I once had a buggy Chrome plugin that was causing communication issues with some servers.
Hope you find one of these solutions helpful. Post back and let us know how you resolved the issue.
