When you say "My browser can’, which browser are you talking about? Are you using something other than Internet Explorer?
Sketchup uses Internet Explorer(win) or Safari(mac) to access the internet. If your IE isn’t up to date or has any security issue SU will fail to connect.
So check that it is up to date and clear its Cache.
So we don’t hang, we check Google’s “No Country Redirect” url. If you’re running another language, that can change, and you can change this to a url you can easily hit, if this continues to be a problem.
