You should get something like this:

If you get something about a connection error, like ERR_TUNNEL_CONNECTION_FAILED, try restarting your router.  Most likely your DNS cache needs to be refreshed (that's the thing that translates human readable addresses like 'www.intuit.com' into numbers computers can understand.. like a phone book).

If that doesn't work

- Go to your start menu

- Type cmd

- Right click, choose run as admin

- Type ipconfig /flushdns

- Then try again. If you want to be extra sure, throw in a restart

Sometimes the DNS cache gets out of whack or out of date... like calling an old friend's number and being surprised when it's disconnected. The flush causes your computer to re-lookup all the numbers.
