Actually I can not connect too.
This is probably a wise servers problem.
Does this happen also with eset smart security (firewall) disabled?
If this happens with eset smart security enabled and doesn't happen with it disabled, you probably must allow the application in eset firewall.
Outgoing connections, tcp ports 80 and 443.
Side note: ESET Smart Security was substituted with eset internet security. They say you can upgrade for free to ESET Internet Security.
