If you literally typed the URL you gave and tried to connect you would have problems, I did too access denied, see image.
However, if you went to the
www.usbank.com logged in and were redirected to www4.usbank.com after login and that failed with connection interrupted, I'm at a loss as to why the connection was interrupted.
Try as Tech suggests and I did previously with your other browser, pause or terminate web shield and try it again.
