You see an “Unable to locate host” message and are unable to browse the
Internet
This problem can occur when you have typed a URL (Web address) incorrectly,
you have lost your Internet connection, or your ISP is having technical
difficulties.
Double-check the URL or try a different URL. If the error message still appears,
disconnect from the ISP connection and close your browser, then reconnect and
open the browser. If you still get the error, your ISP may be having technical
difficulties.
